<Thread to all the people crying OMG Nunu is broken, nerf him, bad balance etc...
He is not broken. His allies are, and by allies I mean champions that can inflate his winrate while leaving their own winrate relativly uninflated: Teemo, Kayle, Jax, Kog Maw, Azir etc. Every champion with built in AP steroid on their AA is worshiping Nunu right now and inflating his winrate, and to make matters worse the season has started and meta slaves have been reseted to a lot lower elo then before so right now everybody who was ranked higher last season with or without Nunu inflate his winrate even futher, especialy in duo queue with a friend. Finaly there is the thing that the games tend to be very short and snowbally with 0 chances of comeback so once that hyper carry Kayle has gotten a few kills and fully maxed blood boil it just goes out of hand to soon with or without Nunu.
What is however a problem is AP ratio that he got on his AA, it made his clear a lot faster early game and consistent, while also providing him with things to do while E is off cooldown, because before he didnt really have much incentive to use AA except in JG. After playing 20 Nunu games I can assure you that just removing his blood boil buff wont do you any good until you slow down his clear considerably.
