With hints about an 'empty throne' in the theme song and references in that flashback we had during the MSQ of the High Houses watching over Ishgard until one worth to be king was found make me think Aymeric will be Ishgard's first king in along time. The current class model doesn't sit well with the commoners because it is very unfair. Aymeric has shown that he is sensitive to that. If Hilda is anything to go by, the commoners want a fairer deal rather than a complete overhaul of society and governance.

I guess the other side of this for me is that the story in Ishgard is moving to a resolution. I don't really want to see it entirely wrapped up in a bow but if everything ended in a shambles it wouldn't make much sense for the WoL to leave and move on elsewhere. Amyeric fits his role for now. They can always come back and see how he is struggling with the weight of the crown later on. Lets be honest, Mewlyb and Kann-e-Senna haven't ever had much a deep dive into their characters either.
