1 simple little change: Red text or Green PLEASE!
So, you finally got into a game of DG; you playing along, when it says "Xmfortmpler47 assisted by Bygeorgeism2 killed Grothomean878". Unleass you've played with ALL the players in that game several times before, you often wonder "Was that a good message, or bad?"; Did we kill one, or did they kill us???".
If the text color of a message was green when your team got the kill; and red when someone on you team was killed, that SURE would go a long way in my book to help decifer what some of those messages mean that flash durring the heat of battle.
