Yeah you know, in seven seasons of a couple dozen episodes a season, I would have liked a little follow up to some of those early season aliens that came through the wormhole. I mean, you’d think they weren’t from very far away on the other side of it. Surely they’d have run into them again at some point? …bloody Dominion. The Wadi and Tosk’s species would have been among those followed up on in some way in my alternate universe DS9. You know what might have been far out, is if the combined baddie forces united in an Axis or Anti-Federation turned out to be the ones who were in the right, opposing a Federation quietly overrun with Conspiracy parasites in key places. For seasons it just looks like they’re being baddie dicks but it turns out they were doing what anyone naturally would given Federation foreign policy actions.
