This, so much. I'm objective orientated in my play and Brink rewards me very well for that. Even spending half my round time respawning compared to some that rarely die, because I'm playing "the ball" I usually end up with 2-3 x as much XP.
Aye, getting rid of the K/D was the best thing for Brink. It should be about winning the game, not how you got there.
Do not go gentle into that good night, Old age should burn and rave at close of day;
Rage, rage against the dying of the light.
