I've had characters I really enjoy who I bring back after a PvP death and enjoy playing. I typically wait until the guys who killed me are gone/retired or whatever reason they had for killing me (plot related) is wrapped up. People get to play their character.
Who are YOU to say that just because you switched subdual modes and proved mechanically better in a single fight to determine they NEVER get to play their PC again?
^ This, however in my opninion if you got publicly murdered/executed/assasinated i.e. having your head removed your body burned ect and your PC is known to be dead, it'd be weird for you to come back.
