The Dol Guldur Fortress map in AOTR is really beautiful, I love looking at this map and moving my troops accross tortured towers and walls. But the main bridge is way too narrow, and also bugged, meaning that units trying to cross it, whether they try to enter or leave the fortress, will just face pass finding issues that, as we probably all know, is one of the black spots of AOTR and BFME in general. Also, this map is difficult to read. Dol Guldur buildings have the same color scheme as the rest of the ruins, so I frequently lose sight of my important things in the Fortress. The big ruined walls that are way too close to the camera also don't help, basically blinding me and forcing me to rotate to find something I'm looking for.
Understand this is not a specific remark concerning this specific map. Same for Caras Galadhon (I just don't know where my things are while playing on this map, it's too wide), same for Minas Tirith (heroes can't reach the gate without aging during the process), same for a bunch of maps that are only made of hills on which you can't build at all (and that is frankly annoying to see a red ghost of your future building that will never come to life, wherever you put it on the map). A lot of your maps are just incredibly beautiful, but this is... too much ? I don't know how to phrase it correctly, to communicate how much they amazed me and how disappointed I was going through all of these little pitfalls on your maps.
