Amumu buffs are not necessary
Why can't Riot just buff one thing at a time. Buff up his W and let the passive do bonus MAGIC instead of true. There's literally no reason to over do it on a jungler that's honestly been in an okay spot for several years. He's going to be so overbearing. The bans are gonna be real. Calling it, Amumu nerfs in a month. And watch them nerf the wrong part.
