In 6.1 i was able to play udyr every game.
And i was able to play him somewhat into 6.2, but by 6.3 i haven't been able to touch him. He's permabanned. It's a shame too, he's one of my favorite champs. Here's to hoping that his nerfs (which are nerfing the wrong thing by the way) actually take him away from fotm status.
The real reason hes broken isn't because of his phoenix stance damage or his turtle shield, it's his bear stance. the 35% ms boost which you can have on yourself 100% of the time means that he can split a lane and NEVER get punished for it. Couple that with zzrot's swifties and runic echoes means you will never get caught ever. And you just slowly whiddle away at the enemy base. You don't fight champions, you just destroy the enemy base. If your team is ahead, you're just going to win extra fast. If your team is behind, you will award your team the map control and global gold they need to come back. Does phoenix help you push waves? sure, but it doing 20 less damage at max rank isn't going to change that.
