The problem with anything, and its always going to be the case, is that you can't make everyone happy. I like simply things, i do NOT like things that look like they are from WoW. Oversized weapons, oversized armour. I know that it makes them easier to see but i do not want huge horns on my sith, i do not want massive shoulderpads.
I am also kind of sick of wearing a skirt, almost no sith in any fiction has worn a skirt and yet my maruder has had to do so for dozens of levels because medium armour seems to be all about the skirt.. I just wants some pants and/or a proper robe over the top.. no more skirts/dresses please. Tunics and robes are the way to go, like in all the movies, cartoons, pictures..
I know this probably has been mentioned and its not really the idea of the thread since its a logn way off but i would kill for cosmetic options. LOTRO has had them for awhile now and that means i could take ANY piece of armour, no matter the stats or whether it is light or heavy, and allow it to be how i look and my stats can stay good. I can have an imperial uniform for my Operative for when she is in town, i can have pants and hooded robe on my sith, i can wear the good looking armour and not the one with the huge shoulderpads and massive, ridiculous cape.
The key i think for most of these things and for most people is SIMPLE and not over the top, exaggerated. huge shoulderpads and things like that, those are things i don't think we want to see anymore, simple robes, cool cloaks, awesome hoods and masks and so on.
