Did the mini rework even do anything for udyr?

His win rate plummeted again and he's back in the gutter.
His mana costs are far more unforgiving in the early game. You used to be able to max a particular stance and spam it at a low cost, but now you're always paying full mana cost no matter how much its maxed out.
Turtle stance no longer has a scaling heal, so only the shield scales with points.
tiger got better I guess?
