Plenty of ways to deal with Tiger Ace. Learn to adapt, anticipate it. Its one unit, can't be everywhere at once. And it shuts down all production for >10 minutes< so yeah its powerful, its a huge gamble because if it gets taken out by a couple of coordinated rams then the player is crippled. Its a high risk, high reward unit.
Wow in another thread defending the ta while not watching the replay. These arent the 3v3 games im sure your used to. Please oh wise one upload your replay of you personally dealing with the ace.
