So some thought on the Tahm Kench nerf from a person who loves and constantly plays kench

Nerf for people who have not seen Devour (W) no longer gives 15-25% movement speed when running away from enemy champions while holding an allied champion. Don't get me wrong is a great nerf! Just I think it could be better refined from an Zeons ask.fm post (Ofcourse this is not a opinion of all of riot link http://ask.fm/ZenonTheStoic/answer/134335957615 ) he says top Tahm Kench is his strongest role so could there be a more refined nerf? I think it could be refined by either increasing his w cooldown(20/18/16/14/12) or making it a static cool down(same cooldown (not affected by cool down reduction)) in my personal opinion tahm kench's main skill comes from sudden decision making of going for an agressive devour or a defensive devour top kench does not really make this decision a lot so the cool down nerf would be more just a nerf to one of his largest damage source other than ult passive.This would also affect support kench of not being as frustrating to go against. Tell me what you think!
