It's firepower is fine. It should be devestating to infantry considering it's a late game, high-cost tank dedicated to AI.
It's staying power on the other hand could be nerfed a bit. Players are allowed to be far more aggressive with them then they should be allowed when a tank is near. I see way too many people charge towards a tank, kill it's supporting infantry, and escape before being destroyed. It could definetly use a health nerf along with a lot of other tanks in this game(panther and elephant).
How on earth a high armor, high HP unit, able to squad wipe in 2 seconds, even retreating, is fine?
