How hard would it be to "freeze" another user's name, or maybe set a nickname (visible only to you) in the lobby?
Too many jerks - and they shouldn't be able to run from their sins.
And yes, you can look it up in game - but you only really know to look if they're already on your ignore/block list or they're toxic -again- in game.
I get it - peepz want a clean slate. But if you're a toxic shit - you shouldn't get a colonic for free at the expense of others who aren't terrible to their team.
