I think thanalan might be fixable in its current state but they need to add more uh..stuff, more hamlets, more landmarks more unique terrain structures,things to do etc etc.

Grid needs an overhaul or better ways to navigate it (Jumping/climbing,underground tunnels that actually connect). nothing was worse than taking the wrong path to a leve when the map couldnt be manipulated. Grid is probably the easiest to notice you're crossing that same river for the 500th time.

Coerthas actually feels like it had some thought put into it even when it reuses a lot of the same tilesets.

La Noscea general shape is alright but it has some egregious tileset abuse(possibly the most easily noticeable besides grid). Maybe keep the layout but add more tilesets.
