I like the pool personally, though maybe that's just me. The pool was added because they wanted to give all four housing wards an area to swim in. I think the goblet used to have a shallow little pool area before, but not deep enough to swim, I think that got removed when they revamped it for the new pool area though.

If the goblet is unpopular though that's good news for me, maybe it'll make it easier to eventually snag a medium plot there than it would be in the other areas. Though if we get Ishgard housing, depending on what they do I may be tempted into that...
