Warwick's damage isn't the problem
his utility/safety is. Giving AS, 30% LS on R and MS+sight to those under 50% needs to be hit b4 damage.
You can ult anyone anywhere because you get so much Lifesteal from the R + passive and botrk that you are pretty much guaranteed to kill the target and make it out alive.
You give a ridiculous amount of free gold to allies that helps way too well with pushing, sieging, dragoning and baroning.
Your E has no real downtime or real cost to have toggled on and gives you sight + bonus MS against any targets with less than 50% health. Why this isn't something like 10-15% is beyond me.
Yet people just want to gut devourer, R damage and R Cooldown instead of fixing his real problems.
Figures.
