I think the idea is fucking awesome and I'd be closely following the community's achievements even though I'd probably not play on it. I think it would be very exciting, though I don't think not being able to be raised would work. You would really have to master fights on normal servers first before you tried anything there and that would make challenges kind of pointless or not as much fun imo. Being able to raise others though, would incur some issues such as people being afraid of doing anything unless they have a raiser around, or people being really upset if they were the only ones who disconnected or simply couldn't get raised and lost their characters in their party while everyone else was saved.
