From the PoV of the scum, my plan means it is more likely they are divided, and more likely they have to worry about another kill in this universe. Why would I propose it as scum?
OK, so suppose that the OU, in it's infinite wisdom, is deciding to send back evilsnail. Then here is something similar to the choice we (or, rather, our teleporter) faces:
He is in a mountainous game with ~10 players in it, and 2 or three scum (depending on if we lynch scum - evilsnail is back). If he likes, he can get rid of the scummiest player, and replace them with a player who has about the same chance of being scum as that player does. But the replacement, if he comes in and is scum, will be a SK without a kill, rather than a member of the mafia faction. Should he make the swap?
Things aren't quite that simple - people come back and forth. But if you are arguing for a course of action that basically keeps the towns as they started, you are pretty much arguing that the player in the above scenario shouldn't make the swap. Which in my view is madness.
"We don't want their scum" is an emotive argument about the apparent unfairness of risking having scum who aren't ours around. But the equal chance of giving our scum in return
Again - anyone who disagrees with me, please please say so. I want to convince the teleporter that I am right, and obviously have no way of telling if I've done so, so I'd like everyone to understand where I'm coming from, and ideally agree with me.
@myko: what else would scum-elli do except scumhunt? Pretty much his only chances of winning are either getting back to U2 or reducing U1 scum. I'd say the latter is well worth his while. I do agree that supposing he's going to be a serious protown force here is optimistic.
These theory posts are relatively easy - serious time to work out who is scum hasn't happened yet. I'll do that in ~24 hours time.
