This is mostly directed towards when the attackers win during a siege game, not quite so the defenders.
At the end of an attackers victory on siege, the defenders should all respawn as peasants allowing the attackers to pillage, rape and burn how they plead. Much like what would happen sometimes you know? Adds realism to the game! Plus it may make the defenders actually work as a team more, cos no one likes to be butt raped yo?
