I think If we had the option to create customized dungeons/events then the development team would be able to make more refined official content. Imagine someone creates a custom event that starts out like the Grand Melee, but half way through the final 1v1 with Raubahn, he retreats into a cave, we follow in and we must fight him and the Warriors of Darkness. Of course things would be changed around text wise and victory/defeated conditions could be altered. But I think it would be a great time killer, think Yoshis raids are to easy? Try the community raid where Twin does DBs and Earthshakers at the same time, followed up by Akh Morn and Hell Wind!
