I respectfully disagree; my reasoning below.

I would argue that creativity has its limits within the confines of the system within which they reside - it falls outside of the typical SCAMPER logic of housing design due to system constraints that are unique to Ishgard homes exclusively at this time. A pillar being in a inconvient place is a issue of creativity - how to you build around or incorporate it into the build - those are your only options. A good point to consider - in all other layouts - you can blend your construction into the existing layout due to the existence of matching partitions/pillars. The option is currently absent which results in a net loss of options - in essence it makes Ishgard homes the lesser option due to the limitations of the structure. It results in more item slots to replicate the same effect possible in all other ward layouts.

Secondly, its no surprise that housing oversights happen - I think a good example of this would be the curved marble partition or the Glade Door partition. I believe that the high-land limitation is merely a oversight; and I think a request for it to be made equal is not unrealistic; its merely a desire in short for Ishgard designing to follow essentially the same design limitations as all other wards - something very vexing to many designers due to the sparse limitations on item budget - which I think you might agree with me is the greatest hurdle to creativity. In essence I do not think the request comes from a place of laziness or entitlement; rather merely the result of a upset of design options which also has a tendency to rob Ishgard of the alpine aesthetic due to folks having to take extensive measures to deal with Ishgard bones lacking matching components.
