Hmmm.
Easy enough. I waited tables for ten years during college. If it's one thing I know, it's how to take orders.

My mage is also featured in this flick:

Under Naka's direction, things were pretty loose. Structure was there, but it was plastic rather than rigid. You have to be flexible or you'll tear your eyes out.
However, based on your reqs, something challenging for a group of 160+ wouldn't be your best choice.
Best I can do is a lvl 125/6. However, there are any number of quests for which there is no footage. Epic is what you make of it in the production, not necessarily the content of the quest.
If you've got the tech, the time, the patience, the vision, and the drive, as well as the ability to be flexible, put it together! Recruit, assemble, shoot, edit, go.
