My issue with these ways to get personal ratings from PUGs (flag caps, # of kills, etc) is that in proper run BG's, one player may have been the most valuable player on the map and not use any of your "requirements" to get any points. These types of incentives discourage playing defense (you get more kills on offense rather than standing by this graveyard for 3 min while it caps) you get fights over who carries the flag, who gets to "assault" a base, etc. Having personal rating come from things YOU did in the BG overall discourages team play, which is the OPPOSITE of what BG's are about and what they need.

I've not gotten to play many Rated BG's myself because I find it hard to find groups, I hate that... but the alternative, while nice on the surface, when you break it down goes against the BG grain... I like how it is now, there is accountability within the group (you screw up, the group knows, and won't invite you back for another BG) and you get just as much credit for the win standing guard at Fel Reaver as the guy who captured 14 flags.. which in a good BG group both jobs are equally important.
