Hmm, he's still better than Shyvana.. If he had a slow remover (like garen) on his bear, that might fix the kiting problem. He doesn't need much change. And anyone thinking Phoenix is weak is weird. How can it be weak, if it allows you to counter jungle almost anyone, farm camps uber quick, and dead heavy dmg during early ganks? Take AS marks and move after aa, so you can land that 3rd proc on the enemy and see their hp bar disappear. He needs more setup than some other junglers, so if you have laners with cc, pick udyr and gank. Or just farm like crazy, and come out as a scary tank/disruptor/peeler/beefy bearmanbirdturtle thing.
Udyr is awesome, and if he doesn't need much to improve tbh, slow remover, or slow after the stun, or even a short leap/tp in bear form (could work like riven's E) is all he needs really.
