I see in nearly every single 12.0 match I have played? So since I exclusively play top tier GRB and see these in 90% of the games I play I consider them “top tier” and they could easily see +1 BR increase with no issues
i think the multipath Hight should be a missile value not a blanket value so players new to GRB and ARB radar missiles can learn and as you move to higher BR’s you have to rely more on notching and terrain masking it would help both the heli problem in GRB and the furball problem in ARB.
the 2s38 can be played in top tier, but i am sorry no other light tank can player that you named, bmp3 too fat and mid mobility, bmd4m2 and bmd4m cant be played at top tier since the atgm are 50% kill/50% do nothing to mbt, bmp2m might be capable but its so hard and fat just like the bmp3, not to forget the 70mm aps pen of the 30mm at top tier is trash, even on the side of a tank
