At riot you if you nerf sated devourer then you need to fix what you've done to warwick.
Riot you hit this pup with nerfs the moment the new jungle items came out cause of how devourer was and you didn't stop there either. Warwick wasn't op till you brought it in. The item was op and warwick has suffered due to it.
His w is now a 6 second AOE attack speed boost and his ult does far too little damage with too high a cooldown to allow that.
Now i understand that buffs to him buff lane wick and blah blah blah.
My suggestion is this rather than buff one of his abilities...why not buff his passive? Make it to where it does %max hp to monsters once it's at 3 stacks. The healing will remain the same, but he will clear camps faster. This will help make up for the w nerf you guys decided to hit him with out of the blue.
