MSQ Roulette actually gives 500 Poetics (200 for the dungeon and 300 for the Roulette bonus) plus a newbie bonus of another 100.

So 500-600 Poetics, a butt-load of EXP, plus high amounts of the other current currencies, for 35-55min of your time.

Seems fair enough to me.

The only change on it I would be in favor of would be allowing cutscene skipping when there are NO newbies in the run (which does happen). You'd still get all the Roulette bonuses as you did offer your time, but you'd not have to waste time when everyone has already done it.
