It is long overdue to look at udyr champion need serious nerfing.
His ability to clear at lightning speed, his ability to spam low mana abilties, his ability to escape via never ending huge speed bursts and immense tanking due to his shield, and finally his monstrous dmg for having ZERO dmg items.
I get it blah blah blah udyr has no gap closer....when you have everything else he doesnt need one. I get it he isnt LCS picked, riot has nerfed MANY MANY MANY champions that never worked in LCS because they are solo pub stompers.
I am not sure there isnt a more obnoxious champion in the game and honestly udyr needs some serious nerfing. Too litle mana costs to swap stances and they are all usable to quickly in succession, too forgiving when you make stupid plays and get caught. It is the lee sin syndrome all over but instead of flashy #lcs escapes udyr just brute forces his way. Sure he can't #insec but he actually does everything else lee does and does it far better.
I am sure all the udyr fanbois will start crying and raging, but i think everyone else know udyr is beyond obnoxious and it is mindbogglingly too simply to play to be that strong and forgiving.
or 
upgrades, he's not going to be able to spam his abilities at all, he's just going to run out of mana exceedingly quickly. Or for example, to be entirely frank, I think Shyvana has a faster clear speed than Udyr; his clear isn't that fast unless you're like a damage heavy Phoenix Stance Udyr. His shield is also fantastically small unless he's AP Phoenix Udyr.
