I find it kind of funny to label randoms as anything.

Aren't we all randoms to each other? Labeling it as "certain something" (good or bad) just doesn't make sense...

So you partied with some randoms and lost? So what? It's just a game, try again and see that you will do better no matter who you party with.

If someone doesn't play as good as you why not teach them?

I love partying with randoms and NEVER did I run into an "evil random who ruined my game"...
I guess I'm just lucky!
