Can we stop nerfing for the sake of nerfing?
Udyr has not been a problem for the longest time. Heck...when Runeglaive was removed he lost damage. Luden's echo only pushes him towards the MS soft cap and has less of an effect than the 10% suggests.
Let alone here is another issue with nerfing the item.
Udyr...doesn't really care. He has 3 very viable building options, 4 if you consider Warrior's (which few do).
Nerfing the item doesn't affect Udyr in anyway except for having a placebo effect which we know the community is susceptible because changes are noted in the patches that sometimes don't go through, and we see winrates plummet anyway.
Just saying...the game is already in a rather unhealthy state. This is one of the times where Riot really should not do anything.
