They dont want the warthunder grind, they want the warthunder consolidated tech trees. (Without knowing about how the grind will be)
Slightly different, even if they most likely walk hand in hand
When you pray for rain you gotta deal with the mudd too.
Card system, with coupons, like in the USSR))). Much more stable and honest, depending on the column you pay from 1 to 3 cards. In the new system, in addition to being able to change the Rank of a weapon, its price will also be changed. Moreover, it will not be attached to anything, except for the opinion of the Snail. If something like PPD works well, then it will cost a lot. I am silent about the cost of the Fg-42, given that topics are constantly being made about him how good he is. Something like this.
Just hope you dont have to pay repairs 
I have to break a spear in favor of warthunder’s tech tree, yes it’s long and tiring but after tier 3, from tier 1 to 3 if you go calmly and without premium it’s not more than a month for at least two progression lines, and you have the possibility to play on the BR that you like best without necessarily having to go ahead and unlock the vehicles of the cold and modern war
oh war thunders my baby. I accept the grind if it gets supported for 10 years plus 
always something new to add to my collection
