"i wanted to completely erase old Amumu"

well there's your problem right there... Riot has said on multiple occasions that they'd never completely erase the identity of a character for the sake of a VU/relaunch (that's part of why Sion is taking so damn long), which is what you did here.

so yeah, it's Amumu in name only, which is just bad reworking.
