kogmaw is a hypercarry

Most win rates gravitate downwards because the game evens up and becomes more 50-50

Kog'Maw, who can burn through objectives like they were made of tissue paper, can easily run away with a game when ahead. However, longer games generally mean he wasn't able to steamroll the game and the teams are closer, so his winrate will slightly drop since it means he (and his team) aren't as far ahead.

The winrate drop is also incredibly minimal, and all of his post-25-minute winrates are much better than his pre-25 winrate.

Yes, Kog is a hypercarry, he's also on the strong side right now so his winrate is high across the board.

ADDITIONALLY, by 6 items, every marksman melts people, but also can position better. So the fact that kog melts them faster isn't as much of an advantage
