After playing however many games after the patch, I can safely say that Kog'Maw is the weakest carry

It's not even so much about the game length, but the strangely contrived way that Riot hangs onto mechanics like his ultimate's mana price increasing per shot when it's meant to be an execute now instead of dealing bonus damage baseline. His laning phase is basically non-existent until you either get Guinsoo's Rageblade or Blade of the Ruined King, and even then he can't really trade unless you max Q first for the 60% attack speed buff at level seven with his W up.

Then you have the fact that he's so much of a niche pick, that you're more than likely going to run out of mana unless you get a constant supply of blue buffs due to your ultimate's mana cost. I just don't know at this point, I mean yeah he can melt teams with a good support, but at this point he may as well just be played mid and as an AP.

I mean shit, he does more magic damage than Corki does, and the other is advertised as the "magic damage" ADC.
