I'm not sure if requesting a specific asset counts as a suggestion, but I did not see anywhere else to put this.
I would personally like to see the Cathedral of Light, located in Stormwind's cathederal district, to be an independent model that can be placed in the game. As it stands now, it is part of sw_cathedraldistrict.wmo, which encompasses the entire district. cathedral.wmo is nice, but is in scarlet colors and lacks the side room and basement that would be nice to have.
If that is not possible, a simple recolor of the cathedral.wmo would also be nice.
