Your queueing situation would have been the same on any Dynamis world, queueing is datacenter-wide. I cleared the MSQ and almost all side content before I moved, so I haven’t had so acute a need to queue for old content, but for anyone struggling (or bored) on Dyna I have noticed there’s a reasonably healthy Party Finder culture. If you put up a PF for a duty, you’ll probably get takers. I’ve taken to checking the Dyna PF listings to find interesting normal difficulty fights for the sake of variety.
