Posted on behalf of the Development Team

Hey everyone!

My name is Jeff Gregg, and I am the Lead Designer on World of Tanks Valor.

Welcome to "Let's talk about tanks! Object 907 edition".

The goal is to highlight specific tanks, one at a time, and really dig down into what makes them tick, how they are being used, and how approaches may be taken to improve them if necessary.

As you read you will see a lot of charts and data. All of this data compares the tank to every other tank of its tier over a sixty-day period. All data is pulled from Random Battles only.

This article focused on the Object 907. Let's get started.

 

Battles and Popularity

The Object 907

A Tier X USSR Medium, the Object 907 Premium Tank uses the 100 mm D-54TS

This tank's usage at tier X is low and barely cracks 1,000 battles a day:

So how is this tank doing with these players? Is it dominating? Is it suffering? According to the data, it is doing ok with a win percentage of ~ 50.3%. The data is choppy, however, and inconsistent due to the low number of daily battles:

Let's take a deeper look into the win rate. An average of win/loss doesn't tell us as much as some may think. As always, we should do is evaluate WHO is using this tank when it comes to skill.

Below we see a curve (representing the skill of ALL players) and a blue curve (representing the skill of the players using this tank). The higher the curve, the more players at that skill level are using the tank. We can see that most players are right in the middle / are usually successful at ~ 50% win/loss. The lower the skill and the higher the skill, the fewer the players.

Now we might ask: "there are players with a 100% win rate?!" or "there are players with 0% win rate?!" Those are likely players that played once in this tank and won or lost and then stopped. Super low occurrence outliers.

This tank shows a draw for more skilled players.

Let's look at the tank's win/loss compared to skill. In the below picture we see two lines, one that represents the entire population's win/loss and another that represents this tank's win/loss.

The Object 907 performs SLIGHTLY worse for most all skill levels, with a trend downward in performance as your skill goes up. See the blue line below the other line? The blue line is the Object 907, where the other line is all tier X tanks.

 

Weapons

Let's keep looking and focus on the weapon (the 100 mm D-54TS)

Accuracy is great. It has an average accuracy of about 75.5%

Penetration is also good but not insane. It has an average pen of ~ 52.8%

Damage per shots that hit is not great; this tank does little damage per hit (in the bottom of the tier X mediums) (super-high numbers in the graph below are the tier X SPGs):

Damage per shot that hits AND penetrates is also low / in the lower range for tier X medium tanks (super high numbers in the graph below are the tier X SPGs):

Damage per battle: this tank is near the bottom of the pack for tier X mediums and damage per battle with an average of ~ 1,755 per battle

Survival, etc.

Let's keep looking at other stats.

How often does this tank survive a match? On average the tank survives ~ 27.1% of the time (in the middle for tier X mediums). But the data is very inconsistent; some days it does much better than others:

How long does the tank live for in a match? An average of 4min and 41s. This is actually in the upper 1/3 of the tier X mediums:

How far does this tank move? A decent amount! It is in the upper 1/3 of distance traveled per battle stats for tier X medium tanks:

How much damage does it usually block? This tank is the #2 tier X medium tank for damage blocking. Here is where the tank really shines.

Conclusions

Summary

So what's the summary?

We have analyzed numerical data on this tank.

The things that stand out the most are:

  1. This tank has almost exactly a 50% win rate
  2. This tank is preferred by skilled players, but it seems to suffer with those players (and interestingly, the more skilled you are the less likely you are to be successful here). Note this is a MARGINAL drop & the average win rate is still 50% (almost on the nose).
  3. The damage output of this tank is low for tier X mediums (both in terms of per shot and per battle)
  4. This tank is a damage blocking monster for Mediums at this tier. 2nd place in this category.
  5. Even with the damage blocking, this tank has inconsistent survival chances compare to many other tier X mediums.

Action Items

Based on this we plan on doing the following:

  • Change the reload time from 8.4 to 7.56 (buff/decrease of 10%, allowing more shots down range per battle and higher DPM)
  • This should allow the tank to fire more often while relying on its armor to survive as it has been doing

The above changes will take place on June 30th.

In order to measure the impact of these changes once they are committed, we need at least 5,000 battles in the tank(s) to have enough data. Once we have that amount of info, we will report back here on what the results were and (if necessary) what the next steps will be.

If you have feedback about this process or have further questions, reach out! Stay tuned here for results of the test and for what the next tank we focus on is.

See you on the battlefield!

K-91 has the worst damage and damage per shot but no changes.

This tank also has terrible damage and damage per shot but the reload is buffed?

907 - Great change, may make it an option for Free XP now but still sour about the K-91 which is worse than the 907 didn't get a change. I've sold my K-91 as i feel it won't get a Buff, if it does (and i'm satisfied) then i can save to buy it back.

It is a move in the right direction but it still won't be able to compete with the 140 and 62-a. It needed to have it's dpm match these two as the whole point is that is supposed to be in between those two but is still just inferior to both. Especially as the other two are tech tree tanks much cheaper or easier to obtain.

If the tank was more popular, it would block less damage. 

It has a slightly atypical armor profile, the people that always aim at the lfp or hatch from the front might struggle a bit vs the 907.

 

 

Better RoF is a good change, 320 alpha with low DPM is just bad at tier 10 unless there's a lot of other factors making up for it other than it's unfamiliarity. 


  

Some people claim Ensk should be tier restricted.   I don't believe their lies. 

Imagine if this forum had only players who actually win more than lose trying to tell others how to play. Would be the best forum ever. Instead, we have a bunch of bad advice from players who lose more often than not trying to tell their betters how to play their tanks.

IMO, they should buff it to have 0.1 second longer reload than the 140 and t62A, not about a full second. Still a step in the right direction.

450k free xp and you wonder why it isn't in play 1k is darn high considering what it takes to get it.  Why are you even looking at this tank?  

 

Complete waste of time... maybe look at the 279e which over 50% of people playing own.

 

Up next the BT-2 Buff  HOORAY! 

 

Effectively the same thing as someone blowing out a candle when his house is on fire.

@Max Chaos 24
I play this game 6 years and have 55k battles.

I think the way which the balancing Team is going is the right direction but tanks like K91, Progetto, TVP, and so on needs buffs. The K91 is the worsest russian Medium but dont get a change? A 907 get a buff why is it so inconsistant?

K91 can also have Camouflage buff to go as tech tree tier 10 of Obj. 416( have one of the best Camouflage of all tier 8s) 140 have better Camouflage that dont make sense to me?

To do buffs because off the statistics is a good Thing but don’t forget do make Tanks special. What are the special characteristics of the tech tree?
I dont want 4 same tanks 140,K91,T62A,430 so make then unique so the people have fun to grind!
As example: Badger tech tree :
All tanks of the Badger tech tree have great dpm,good gun stats, good amor but they are pretty slow
If u look on Badger look at statistics and try to overthink are the characteristics of the tech tree on it?
Badger have good dpm, good gun stats good amor and he is pretty slow
so all characteristics are represented
If the statistics are bad u can buff the dpm or shell speed a little bit or the horse power for more mobility.

u don’t must buff dpm there are so many ways to make the tanks better!
Thx for reading I hope u can understand this in my opinion.
This game have my full heart blood but things like the K91 no change hurt me so much!

I think the reason is obvious....the obj 907 is a money maker that people basically need to buy to have and the k91 is an easily earned tank.  Other than that why bother buffing such a seldom used tank and not the other...

D'accord sur la chèreté des tanks et autres accessoires.

Du grand n'importe quoi pour un FREE TO PLAY.

This gets a reload buff but the k-91 doesn't?? Oh come on. Their is obviously some favoritism going on here. Someone at WG clearly doesn't like the k-91 lol

I mean the reload buff barely makes it better than the K-91 DPM wise lol and the K-91 has better pen and accuracy. K-91 needed a buff to get a decent sample size for analysis if nothing else though. At least the 907 is not longer completely useless

This is a step in the right direction for this tank. I think both the 907 and K91 should have dpm similar to the other Russian meds but this at least helps.
