MSQ Roulette hasn't really been an issue on Louisoux, either.
PvP Roulette is not meant to be serious. Most people there are for XP. Adding a ranked roulette for Frontline is likely what you want.
The raid situation seems questionable, yeah. That's why in some games, your gear is locked once you enter, but otherwise it also seems the harder raids should also give better rewards so people are happy to see them.
