Is Wits End kind of broken or is it just me.
I mean this guy
, Literally buys
and become immune to ap dmg. If he is low he heals like crazy and is unkillable. 
buys it when necassery, you play ap, and can't do shit to them, all u can do is to shove lane. This item alone breakes the rules, and make any mage vs users of this item useless, unless late game , when u reach
. Imagine 1 item forces u to play 15 min longer the game to even be usefull, but the games are ending in 25-30 minutes. Master is just buying it even vs full ad comps, because he can, its nice xD.
It's stupid, its almost the same as riven's conqueror
combo, which make her a tank, but to melee vs ap version.
I would not change mr stats, just nerf the heal from it lol, especially for melee.
