What they shoud is reward tanks and healers even more. Right now is not enought.

Forget about 750 gils, give 10,000 and people will play tanks and healers roulettes to get money, and no one will have to wait more than 10 min to go in.

The thing is, that 750 gils for have to deal with a low level dungeon were very often we find players that refuse to talk at all and will just do everything quite bad (Not always, of course, but the danger is there) is not enough. Takes time (30-90 min) and your only reward once you are lvl 50 is... Those gils and 10 mithos the first time. Not enought. You are better doing any high level dungeon without roulette with party finder. Just find other 3 guys to do it and you'll finish it before, probably get more money (from mobs), same repair cost, and more mithos and philos (Wich can be used to earn gils too)

The problems is that the roulette bonus right now is useless for being too low that no lvl 50 will do the dungeon for it. Of course, some people will do it because they like it or they want to help, but not for the bonus.... So, bonus is not enought.
