I'm all for this. Suppose I'm in a static party, and I just got a good friend of mine to play this game. 3 weeks later he's all geared out, and ready for coil but can't run with him because my party does not rotate. I wouldn't mind running it with him, without the loot drop too.

The people who will miss out the most are usually melee and non-bard DPS, due to the current accepted standard of coil party composition. Putting it on DF or allowing people to run multiple times with other people gives us a chance to help such people too.
