Udyr infinite shield
I just faced an Udyr abusing an ability to shield constantly with CDR early game. He rushed armor just kept shielding and farming disregarding the enemies damage. Eventually it got so bad that he was way ahead in farm despite taking my full kit over and over. He started tanking me under the tower and ignored me while he took down the towers health. If he was low he ran away and used healing potions. I don't think riot intended for this to happen. Basically in theory it is impossible to kill him as he has mobility and an infinite health pool using a shield and pots. Furthermore he takes down towers way to fast. He was actually tanking me and the turret at some point. Eventually it wasn't about skill or landing abilities it was a farm and level difference that I couldn't stop. I'm not that good at league probably, but I have been in game developing and I know for a fact if I saw what I saw It would be nerfed immediately. My last match before this is an example. Eventually I just stopped trying because I realized it was pointless.
In any-case, I will be abusing these mechanics until they are fixed as they will sure fire make it easier to win top lane if I play this champ.
