Show teams current damage dealt, just like in Arenas
Two reasons:
1) It can communicate valuable information how a fight goes. If you see your teammate damage meters go from 400 to 800 in a short period of time, you can tell its going your teams way.
2) it will shut up most blamers/ragers/premade duos. Lets be honest here; its almost NEVER the huge damage dealers that complain, flame and blame all the time. Its always the useless, who are too bad to understand the main reason that you lose the fight is because their incompetence. Its always the same; you get hard flamed by some premade duo and when your team is eliminated the second after, you see that you have 5x their damage dealt combined from the same fight....... I think this will almost unconsciously keep ragers from start flaming if they see how much better their teammates are...
I see no reason why hide this statistical truth when we present the numbers in the match summery anyways....
