Riot. Do not nerf Devourer / Trailblazer. You confuse source and result.
So many junglers fail horribly in the new jungle - and what is done? Trailblazer and Devourer (. instead of Warwick...) are getting nerfed. Not realizing for why these are the most picked Smite choices.
1.) Trailblazer -> The new jungles item have horrible mana susatain, monsters have more health - thus you need more abilities to kill them - Trailblazer is a MUST on an ability&mana dependant champion or you will have to back after each 2nd camp. Nerfing it will only drive champions such as Sejuni out of the jungle.
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 (5/1.8 = 2.78 Attackspeed). 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.
3.) Pouchers is bad by default. Picking it gives you away and allows your opponent to easily read your intentions. Even if it gave +60 gold instead of +20 it would't be borderline-too-risky to pick it up on any other champion than Nunu(in higher Elo's).
