If I'm in Quick Play, solo, with another person, or in 6, I'm practicing or goofing off, end of story. Even if I'm "trying" (playing a char I have a lot of time on) I'm just practicing. I know it's the only "real" mode right now but it's rediculous to expect 5 other people vs. 6 other people to all be on the lets-try-our-best-on-our-best-characters-in-an-awesome-comp all the time. All going 1 character can be fun and it's the most obvious way to tell people aren't tryharding but generally speaking, unless everyone on voice agrees, it's just practice mode.
