Particularly on Bronze I couldn't care less because in most cases it's what the player does with the character that's important, not what level they're on. You're much better off having a good player with a low-level character who understands the importance of working together than you are with a Level 15 who ignores objectives and just runs off on their own to get killed the whole time.
That said, I haven't seen much of this phenomenon. What I've noticed a lot more of is individual players just leaving if they don't like the makeup of the team they've been matched with.
