I know this is going to be controversial but for one time instead of talking about russian bias I want to address the wheeled vehicles ;
This class maybe fun to play like all other liight tanks, however IMO they have too much advantage over the other light tanks.
Speed could be ok but when it's combined with the "star trek" laser accuracy of the gun and the fact that almost every AP hit result in tire damage (wich do not even immobilize the tank) it is immediately clear they are too strong compared to all other light tanks..
My suggestion is to leave the speed as it is but reduce or even erase the autoaim modality wich require ZERO skill and givce and absurd advantage over all Others, and increase the chance that an hit on the tires force the vehicle to stop and use repair kit to move again.
