Tiger ace is bad, it dies so fast even to a upgunned sherman rofl.
Lol you must be bad.
If it shoots much faster than a upgunned sherman, has longer range in AP mode than a upgunned sherman, has more DMG then a upgunned sherman, more HP, more armour, ect. (unless stats changed)
How in the world could you let the sherman deal more then a measly bit of damage on you?
