First, I agree that he gets a bit too many turns. His counter shouldn't give him more than one attack, and his speed bar regeneration needs to be toned down a bit.
But I do not think, like some people, that he is a great menace or needs to be majorly nerfed or removed from the game.
As pre-launch players remind us, he is not a big factor in the current end-game. But he's important for those of us in the 40s and 50s.
Why? Because Jedi teams dominate the meta, and he's a primary tool against them. His stun, counterattacks and speed are very important in dealing with the very common multi-healer Jedi teams, as well as those using Ima-Gun Di for counter procs themselves.
Simply put, as annoying as he can be, without him, things would be a lot worse. Jedis are one of the few options for a really synergistic team right now, and removing one of the counters to those teams would be a mistake.
Quit 7/14/16. Best of luck to all of you.
