For the regular 8 man and the 24 man raids, I think a system where you get a bonus to your roll based on how many times you've done it that week would work.


But for a performance based roll, I don't think a bonus for doing good would work, but rather a penalty for doing bad. I don't know how it would work for tanks and healers, but DPS could have a baseline that's fairly easy to beat as long as you dodge AoEs and don't get yourself killed constantly.

Maybe for healers, penalizing them for party members dying to arenawide AoEs (if the game could tell the difference between them and any other attack).



Of course first timers reasonably could be exempt from it.
