I'm totally against KDR... killing isn't everything. However if the devs implement some mathematical formula that takes into account all things(revives, kills, heals, vehicles destruction,etc...) and call it something like "Battle Effectiveness"(BE...curious ) then they can show that.
How about stats for the individual/squads that are beneficial to the faction. Eg objectives captured, orders followed successfully (like blowing up that tank that's pinning us) and nid infestations exterminated to name a few.
