Scale the "Adventurer In Need" Bonus

[Rexxus]

The Problem is people don't want to tank or heal, there is a vast majority of people who only want to play dd, even though they are bad at it.

That's what this change would work to fix

Offer an increasing incentive for people to play needed roles (Usually - Tank or Heal, though in the case of Alliance Raids, it can on occasion be DPS). Eventually the reward will be high enough for people to opt in.

I feel like this would be an overall easy addition to duty roulette system that would skew participation in a direction that directly benefits everyone's queue times.
