Kog'Maw has been the same champion since patch 6.24
I see many people complaining about Kog'Maw being too strong, suggesting many changes to the champion blah blah blah. Why do people care all of a sudden? Why wasn't he this OP back in 6.24? It's very silly to see this sort of outrage for a champion that has only recently increased in popularity since other ADCs got nerfed. Kog'Maw is hardly a problem because if he WAS actually a problem it would have been present in January last year. It's not Kog'Maw's fault that his supports are meta, very strong, and are more reliable than heavy engage supports. It's not Kog'Maw's fault that last patches top tier ADCs got hit with direct or indirect nerfs. It's not Kog'Maw's fault that.....well, you get the idea.
After his revert he was considered dumpstered because of no one really knew how to itemize. Should we still build Rageblade on him? Back to the old Trinity Kog? Let's play AP Kog'Maw! (This resulted in his nerfs in patch 6.24. They added 1% increase on W but if you do the calculations its not that much per auto). Kog'Maw since then has remained the SAME champion with the SAME build. The champion that was reverted in August 2016 is the SAME champion now. Look at what has changed around Kog'Maw. The supports, support items, assassin viability, shields, life steal, runes etc. If you keep tunnel visioning on what the problem is to YOU then you may actually change something that is unnecessary.
etc...) right now his lane damage is too high because of sustain nerfs and shit like that. he is the same champion, but the game isn't same around him so he has to change with the game
