My expectations change depending on the roulette I'm queuing for. I only queue as tank/DPS depending on how much time I have to wait around.

*Leveling roulette: If the dungeon is below level 50, I'll tank slower and take 1 pack of mobs at a time unless the party shows exceptional DPS. Higher than 50, I'll usually tank a lot more mobs, depending on the iLevel of the healer. As DPS, I expect the tank to do the same. We tons of tools at our disposal at 50 and above, we should use them.

*Expert roulette: pull everything, destroy everything. As DPS, I want to destroy everything as fast as I can and test out different rotations. As tank, I want to be able to handle as much as I can and provide a smooth ride for everyone. In doing so, I expect DPS to be laying down the nice damage.

*Trial roulette: Anything goes. I expect there to be new people every now and then and thats okay. These trials only need simple instructions for new people anyway, its not a big deal if we wipe a couple times.

I never try to speed run everything, only content I think it is appropriate, like Expert roulette, 50/60 roulette, or farm parties.
