Add match type to sccoreboard!
In low elo there are a lot of players that queue thinking they're in a norms match when in fact it is a ranked match and vice versa. Leads to players caring too much when it should be a no-stress fun game, or caring too little when others are trying to climb. You have a "5v5 RANKED" or "5v5 NORMAL" in the lobby.. players seem to not look at that. Add that text to the scoreboard in the game. That way there is no mistaking.
