kog is a problem in general. now that he's returned to get massive free % health on his damage, and rageblade exists, he's just too good built with cheap on hit items and rageblade.
rageblade needs to be reworked so kog can't do the insane dmg that he currently does.
he was fine when people were still building him trinity (albeit a bit weak) after his rework revert. but once they realized you could still go rageblade it was all over. he is a hyper carry with a one item spike.
its busted. no hyper carry should spike at one item. between kog, trist, and twitch there's not much reason to play anyone else. I'm a Lucian, Ezreal, MF player with a bit of trist and its pretty miserable right now. I either pick trist or put my team at a disadvantage.
they need to look at nerfing trist E further, getting rid of phantom hit on rageblade and replacing it with something else, and reworking twitch to not be as cancer as he is. because twitch is pretty weak in lane, but in a meta where lane bullies often aren't worth it, he gets to scale up. and that means he either is oppressive like he is now or completley unplayable.
