You should be able to "Execute" a player you defeat. Cut off his head, or cut him up so he can not rez. Forcing him back to his Totem.
If i lose to a player, I just stay in ghost mode....follow him until I rez, then fight again...knowing that I've already gotten a hit or two off on him, he is eventually going to die.
By "Executing" your foe, it would force him back to his Totem.
I think this would be a good addition to the game, would also stop the "Griefers" so when you kill them, you can send them back to their totem.........Just my opinion.
