Is it not sad that mundo is still weak despite his super massive powercreep?

patch 7.15

patch 6.19

Masochism Masochism Minimum bonus attack damage increased to 30 / 50 / 70 / 90 / 110 from 20 / 40 / 60 / 80 / 100. Maximum bonus attack damage increased to 60 / 100 / 140 / 180 / 220 from 40 / 60 / 120 / 160 / 200. Cooldown reduced to 6 seconds from 7.

Mundo is definitely struggling, but is it a fault of his or a fault of other champions and/or items becing powercreeped?

I mean, jesus fucking christ the dude got a free 30% total MR steroid with max E with no compensation nerf and he's still garbage.
