Well my hope would be an actual Forsaken city would necessitate more than the 4 styles of buildings that exist.
I like the lab structures and the ‘manor’ would work well as houses. But the inns are super barebones, no pun intended. Now these structures when they first appeared in Northrend made total sense as most Forsaken settlements there were about function. Same with the buildings in Silverpine, Andorhal and Hillsbrad as those were recently conquered.
I was always really bummed the only unique thing Brill had was a stable though. I missed Gallow’s End. I’d have preferred reworked human buildings with gothic spires and more than decorative gargoyles on them. Imagine inns where instead of pine boxes (or manners with just a bed) you had luxurious purple satin coffins and the like.
You could just go nuts with Gothic architecture. The Great Value Tim Burton mad science stuff was fun but there aren’t even chairs for Shadow’s sake. There’s no spot to really hang out.
