A long time ago, New Players started with ~3-5 Garage Slots and got 1 every new nation
Then, maybe ~1yr ago, it was changed so that New Players start with ~7-8 Garage Slots and don't get more with New Nations
So they actually made it better for folks overall, not having to wait on Nations to get the bonus slot
WG would get more people to play the line if they had the tier 1 and a garage slot waiting for tankers. Just a marketing suggestion. I have more than enough slots to add tanks.
Haven't seen too many Zizka premiums also. It's a tough tank to play and the price tag is not for the masses.
It will be on discount next month.
