How can you keep nerfing Udyr's damage?
If he had the same base damage for 5 seasons and is suddenly problematic, then maybe the problem is something else. Obviously it's the mobility and stupid, snowball-heavy, gameplay. R from 220 to 165? Why don't you just delete the champion from the game. I can't remember the last time I saw an udyr at the top of the damage charts for a ranked game.
Are you going to shift power in to something else? He is only a 3-ability champion already.
