I wanna see what everyone else thinks, and maybe its just me but IMO I feel like both Elinhir and Falkreath had so much flavor and potential as zone hubs, but were squandered by turning them into dungeons. Elinhir especially because it had this mix of nedic, redguard and colovian elements with a mages theme that wouldve been great as a zone hub for the area of Hammerfell south of Craglorn. But its impossible to fix because of how intertwined the dungeon is with the Craglorn questions.
Meanwhile I think ZOS couldve done a lot more with Falkreath's famous cemetety. Definitely wouldve been a better dungeon choice than reachmen and minotaurs but that's just me, what does everyone else think?
