QSS alone not enough for WW

Banshee's Veil instead of QSS? Gives actual defensive stats and good survivability.

nerf an irrelevant champ!

Warwick needs a rework in general (Malzahar also has a similar issue and his ult needs changed too.)

uh...not really. ww isnt really the first thing that comes to mind when i consider champs that adc hate. No he doesnt blow you up instantly. in fact i find i normally can just beat him as adc after getting core items if he tries to fight you alone. But dealing with people trying to focus you is jsut something you have to learn how to deal with as an adc. You just learn from experience. Against some champs there really will be squat you can do (i feel that way agaisnt rengar for example). Whatever. Just fight with your team and do all the damage you can before the anti carry kills you, and hope that the time/cd/whatever spent was worth it. if your team wins the teamfight then it doesnt matter than you died.

normally ww doesnt quite kill you with his ult, even if you dont have a cleanse. Then as long as you have your trusty bloodthirster/bork whatever and good damage you generally heal about as fast as he does damage. its no big deal. hes more annoying for ap champs or bursty champs because hes a bit too tanky for anyone to kill in one rotation

Sated Devourer is really balanced.
