SE could change the way roulette works.

It works right now like this: Just making up numbers for the sake of argument.

X Roulette: 25 Soldiery, 50 Poetics, Adventurer in need bonus (Tank) 500 gil.
That means every job gets the bonus tomes and the tank gets the tomes and the money.

What I propose is that only the adventurer in need gets everything. In this case, only tanks get the bonus tomes and money, no other jobs. There are already enough DPS and healers queueing for non-roulette anyway, that's why tanks are needed in this case. DPS and Healers are already queuing for dungeons on their own. That would make more tanks queue.

But the pessimist in me knows someone will try their hardest to screw over everyone else.
