I've thought about starting a dynasty league - but honestly, my fear is that some from my home league would join (but they are mainly guppies), so I think they would quit after a couple championships by me or having an inferior team that doesn't "start over" like in redrafts. And as commissioner, I would need to solicit new owners for the vacant teams or the league implodes. I play in the keeper leagues from PhenomsFF - and I am confident that if anyone left from those leagues that the teams would get claimed and the league would survive. Playing commissioner I feel could be a lot of work all for not within a years from start-up.
