Reasons like the fact Udyr has managed to be a top-tier ban-worthy option for months in spite of past nerfs in both top lane and jungle have nothing to do with that, I'm sure, nor the fact that it is a defensive mechanic that is based exclusively on RNG rather than the actions of either player(outside of stacking the passive with the stance spamming you'd normally be doing anyway regardless of whether or not Udyr had a passive that benefited from it). He's bounced from being in that FOTM OP group to just below it depending on his current state and public perception of other champions at the time for ages, and while obviously the dodge mechanic being removed hurts him it is definitely a good thing for the game rather than a bad one.
Since I'm too lazy to respond to the frothing in your PM: You get shit from me and lots of other posters because it is painfully obvious every time you post that you have absolutely no idea what you're talking about. It's pretty funny you're trying to appeal to experience here since you've been posting in this thread for what must be months now without hitting level 30 and by failing to do so you're continuing to play against unskilled, inexperienced opponents who aren't participating in a game that is even reflective of normal queues at 30, let alone of higher ELO ranked or the competitive scene or whatever. You have this insatiable need to comment about everything but your opinions could not be more baseless and irrelevant because you're not even playing the same game as the other posters in the thread. And yes, I do play Udyr(unlike you, amusingly, since you mentioned you don't even own him), but that doesn't mean I have some bizarre perception that everyone I like is balanced perfectly. One of the game's best characters is toned down some with a nerf through the removal of a mechanic that isn't particularly fun to play against or skill-oriented. If it hurts him too much they'll just un-nerf Turtle some to compensate. You're ridiculously overreacting, as usual.
