Everyone has bad games. If they're in the same rank as you, they're roughly the same skill level as you, but perhaps in different categories.

Well people have to start from somewhere. It's a ladder system, not a pro gaming mode. Anybody is allowed to play, period. But that doesn't mean anyone is allowed to be a jerk.

I'd rather have a teammate that's bad than a teammate that's a jerk. At least you can cooperate with the former and utilize teamwork to cover their weaknesses.

Ya, I think exactly the same. If you are going around telling people they suck, you shouldn't be playing multiplayer games, let alone Ranked!

Telling them that they suck doesn't help your team, if anything, it makes the guy play worse.
