I agree.
Devourer is completely fine on basically anychampion - but Warwick.
The problem with Warwick is the "Attackspeed" he gets with his ultimate. Too many hits in not enought ime.
I mean seriously, so many junglers fail horribly in the new jungle - and what does Riot do?
Nerf Trailblazer and Devourer and Warwick instead of wondering for what reason these work so well...
1.) Trailblazer -> The new item has horrible mana susatain, monsters have more health, Trailblazer is a MUST on an ability&mana dependant champion or you will have to back after each 2nd camp.
2.) Devourer synergizes well with attackspeed. Normally attackspeed is a lategame stat. That's what Devourer is balanced for this. However Warwick gains MORE attacks per second than a champion would maxed out attackspeed/full build could ever get. Devourer is not the problem here.
If his ultimate had the same base damage but 3 hits we wouldn't be talking about wether Devourer is op or not right now.
