The issue is not the RP and never has been the RP.
If RP was at stake, everyone would full loot everyone cause you don't want your enemies or your victims attaining more power to come back and kill you, but rather want to leave them as powerless as possible. You'd never get a single thing back after a fight where you died, ever.
You'd also gang anytime everytime when possible, because thats one of the few ways to ensure a win even against those who are more skilled than you.
I would not want to play a CF where people played entirely on their RP without worrying about game mechanics and player courtesy. That would be stupid, boring, and ultimately pointless.
