Incentives to NOT queue as DPS

[Felis]

Just add a bonus amount of whatever tomestone is currently relevant to the 'Adventurer in need' reward. Might incentivize more people to roll Tank or Healer at least for one roulette a day. Though, at the same time it could also have the opposite effect of tanks / heals not queueing as often because they cap faster. *shrug* I don't really know a valid solution to the issue.

Put in rewards that you want after leveling up, not during leveling up.
Like a 5% chance to get a rare mount after finishing a duty roulette at level cap with 100% random people. Each roulette will have it's own mount as a reward.

Or it can work also with a premade group, but every random player will add 2% to the 5%.
