In short, since evryone has thousands of supplys and its activated almost all the time the supplys lose thier meaning they could be removed from the game and wont make a difference except mines and heals because those are used more strategicaly. Most of the problem is with the dmg boost, speed boost and armor boost. My idea is these three boosts (dmg, armor, speed ) would be only activated with boxes in battles , so the basic stats of your tank matter more when fighting
