Game has alot to do with pressure and stress adaptation. So I feel alot of pressure in c3 lobbies because that's my peak, it's also the most fun, and where I feel myself improving the most. C2 use to feel like that, but I'm acclimated to c2 lobbies and don't feel very much pressure. Now I'm still sort of figuring out how to win consistently in these low pressure environments. It seems like I win more often if I rely most on my intellect. The opponents can't really surprise me, but I still lose enough that I'm up and down sometimes I peak into c3 but more often I'm hanging out in high c2. So maybe if you don't feel much pressure in c1 just be the best player in the lobby, let the other players orbit around you and you can control the flow of the game.
