Just tried out jungle Kog'Maw a few games
and holy hell is the damage absolutely insane

and everything just MELTS. Doesn't matter one bit how tanky they are. I've always loved Kog. I've tried playing him ADC. I've tried playing him AP mid (before his mini rework). The problem with him was that he was very vulnerable as an immobile carry with no hard CC. Or maybe I was just bad at it. I'm not claiming to be DoubleLift here. So I saw some vids about playing him jungle and decided to give him a try. Krug smite buff paired with his innate super attack speed makes clearing a breeze. Best part is you can get around his vulnerable laning phase for the relative safety of the jungle. No flashless Kog lane to camp.
Once you get 2 items you absolutely shed people. Everything after that is just icing on the cake tbh. Not only is your damage ridiculous, but its also hybrid damage which makes itemizing even more difficult.
If I'm being fair I honestly think its a bit OP. If the enemy team cant get toyou and instantly blow you up, you just annihilate everything.
Give it a try! Its so much fun. You won't be disappointed
powerspike work in the jungle tho????
