I'm a fan, except I think the leader ability is a bit too much. I like the light side/dark side components, but Yoda's leader ability (which is designed around tenacity) only grants an additional 35% tenacity, I think +50% tenacity in addition to the rest of the leader ability is more than it really needs and just a little over the top. Just my opinion though. The rest of his abilities seem fine, and I wouldn't be too worried about his damage being too high considering the recent character releases ;)
