Then don't run the roulette?
You can cap on weekly tomestones in 2 or 3 days doing just Expert and 50/60/70 roulettes.
There's levelling up, but you can gain a level with the other roulettes each day, and that's not going to matter anyway once you get your jobs to 80.
So people who vote no can be kicked?
Like I said, if you have two options, whether by voting, or by the presence of newbies, or whatever, then you may as well have two roulettes so you can choose which one to go into without messing about with voting or anything. At that point, you're not going to get people doing the one roulette that actually matters.
This is still a Final Fantasy game. Story comes first, people want to experience the story as it was intended, not to watch cutscenes jumbled up in the Inn.
