Warwick

You should have played with the old red smite and warwick before everything got nerfed. Warwick is nowhere near OP now especially when you compare it to patch 4.20

His ult only procs red smite ONCE...

Why is this an issue?

You complaining about warwick being op with red smite tells me that you either dont play him or dont play him enough. Warwick is vastly underpowered and broken in that regard. His ult which has too short of a range, does little damage, and doesn't scale enough with items, can be interrupted by pretty much anything from any champ. I have been interrupted by the champ im ulting more than once and the cd doesn't reset. If Darius is interrupted his cd refreshes and other champs either cant be interrupted or their cd refreshes. Red smite on ww is the same as red smite on pretty much any other jungler.
