Will the typical "awesome" group (tank, damage dealer, support) still be the best option for this type of quest? Or, are there advantages to having some less optimal classes, such as necromancers, thieves, etc.

If there are no advantages currently, would you consider putting some into these quests which might provide "shortcuts" for these types of classes? Example, a quest where an NPC will freely offer info or bypass certain tedious steps if you have a certain class in your party.

Poorly worded, but I am heading to work and I have no time to flesh this post out. Do you get my drift?
