Semice was rank 1 with 56% 1v1, I was rank 3 with 48% 1v1, ignore winrates. That guys bad, he might have won 73% of his games, but he'd lose 95% vs. me or semice.
Who you play matters much more than how often you win.
There's a common theme in every game linked in this thread. The guy doesn't know how to pick, and he clusters in every game. It's a losing strategy.
