I'm amazed by all theses players who forgot this :

When you use the Roulette you get bonus xp/gils/tomes for doing random content to HELP new/leveling players
You get rewarded for using your time to help others.

If you don't want to help new players then don't it the Roulette button. But of course don't get the rewards either.
There are other ways to get tomes anyway.

To whoever suggested it first, I find that removing the daily reward for player quitting as soon as they don't like it, is an excellent idea.
