O If the engine overheats, the T34 will be slowed down eventually canceling the RAM
This was to account for the fact that heavy vehicles cannot maneuver out of the RAM ability as easily as light and medium vehicles. Against heavier armor, RAM now has a chance to fail based on armor and penetration. RAM has been adjusted to be countered through movement vs. The role of the T34 is that of a flanker meant to exploit enemy weak points with hit and run tactics. Focus on improving T34 viability and better balancing RAM for mid-late game.
