I would not want this. I would like to see less roulettes overall -- or to see more equalisation between them (e.g. MSQ roulette should include the endgame trials/dungeons). However, I think it'd be great if they made an achievement for clearing ARR/HW/SB dungeons (eventually) at minimum ilevel, with a neat little title attached. As it is, though, we have too many roulettes to begin with.
