I've said this a few times already and i will never get tired of saying it.
Its 2012 we have a long history of MMo's and their UI's , the standard UI elements and all its details has been invented,accepted and approved by millions of gamers years ago.
You don't have to think or improvise on the standard features that are blatantly missing from swtor, the wheel is round and not hexagonal.
Furthmore since everyone is different custom UI's and mods are the default improvement over this basic UI, end of story.
