Rabanstre once a week; ok, we can deal with the wipes, challenge is fun.

Rabanastre once a day for tomes; dear god we hate this.

Once you put something into a roulette you expect people to run once per day or so, the last thing you want to do is make it hard or a wipe fest. Keep in mind whey they started the roulette we massively overgeared all of them; Rab is the first one most people won't, and its very trivial to wipe people in it even with boosted HP.
