Okay.
1. Too technical for me
2. See 1
3. Not a bad idea but 1 character per player is really the best option for a hardcore RP game. Alts are an enemy of roleplaying because they can be used for metagaming so easily.
4. I've played on servers where all these points are already instituted. They all work well in practice.
5. Might work.
6. Death is death. Level shouldn't matter so much. Part of the point of RP servers is that level is secondary to story anyway. The more that control over levelling is taken away from the player, the better.
7. Generally ok. But reliance on twinks and alts is bad. Neither should happen on an RP server.
8. Better to put the ball in the player's court to do this kind of thing. But it's a nice fallback if they can't be trusted to RP (which lets face it, few can). Don't know about chopping text automatically though, in practice it would have to be done right or it would look very very silly.
9. Might work. Seems a bit odd though, surely some characters would be unemployable...
10 and 11. This is putting the cart before the horse (admittedly, most servers do exactly this, to their eternal detriment). People shouldn't be mandatorily given quests or questlines. Rather, situations should exist in the game world and it should be up to the player how they wish to relate or interact with those situations. It should all be optional, not just automatically farmed out upon a certain action like making a team up or whatever. Because what if my character doesn't give a shit about saving the princess or stealing the trolls' loot or whatever else? My character might have entirely different reasons for forming a party, staying in a party, or leaving it.
