Here's my Opinion:
I think they should take away the scoring system completely. No rankings 1st, 2nd, 3rd, etc... BUT...I think we should be able to look at our OWN stats (K/D, Hit %, kills page, etc..), but unable to look at other people stats. That way, there wouldn't be much "Hey, I'm better than you. My score says it all. Why would I waste my time in the DA with someone whose score is worse than mine." kind of stuff going on.
