Nunu, and the very sick yeti.

Nunu went from a 46% winrate to a 54% winrate in a single patch. Who thought giving a teamwide free AP buff was a good idea. Old Iron Locket got a rework because giving a team 20 MR was considered overpowered. Yet 40% AP buff is ok. (Oh but don't worry its capped at 120. Its -Only- a deathcap without the passive).

He went from a jungler who was unhealthy because he was useless to a jungler who was unhealthy because he was broken in a single patch. Good job Riot [slayer-pantheon-thumbs]
