Maybe if we get over the scepticism we could start thinking about how to implement it?
It doesn't have to be standard DF que. It could have different matching algorithm, starting with every job being allowed in the party only once, ensuring that there is awlays one brd/mch etc. To overcome the composition obstacle.
There could also be prequests for it. SE wants to add the training hall, then it could be requirement to pass certain trials there to unlock the option.
Steps to make it more viable for DF could be developed.
