whats with kogmaw?

what the deal with kogmaw? he used to be in an ok spot before all the adc changed ages ago. then a number of nerfs he was in an ok spot with the witts end first build that came from korea i think. then they changed him back to almost old kog but kept the mana cost on w. the mana cost on w alone was a big hit to his laning phase.

in terms of adc he was still pretty bottom of the pile. nor was his midlane very good he needed around 30 mins to get going and vs any kind of assassin usually just fed.

the question is then what with still nerfing him .. the base dmg reduction on E i guess is understandable to dial him back if u felt he was to strong but its not like he had great wave clear as adc without huricane, same as most adc. so why gut the ap scaling? was there something about him been played mid that riot didnt like? i thought champion diversity was a good thing? i just dont see the logic behind it. does anyone know the reasoning?

seems odd to be nerfing adc when adc is basically a useless role right now

are they just trying to make him into a urgot level meme? lol

there seem to be a few champs that riot completely gut and just leave as a bait for people that dont know any better
