Speech balloons would certainly help, and while it's certainly a "want" and not a need it would go a ways towards bringing the rp action back to the characters and not the chat windows.
I'd also like to see a bit more in the way of action emotes for rp. Again, more of a want, but this is a good place to put them.
Also, Some form of the Imperial Trooper Armor that isn't basically as expensive as the CE set. Because that's all I can think of that I'd even buy that for. And that's too much to spend for most of what I already have. I guess this could be summed up in short by make more social armor's, and ones that don't suck. Imperial Uniforms and Trooper armors that aren't class and armor restricted and are purchasable by the majority. Why should such public and symbolic thing as the trooper armor be so restricted? The Republic side gets Trooper armor from the get go, why don't the sith?
I'm sure it's already in the works but a little deco flexibility for the ship would be nice too. Maybe even a creatable instance on your factions capital planet that you can use as your "office". It doesn't make sense that a Sith on the Dark Council or the galaxy's top Imperial Agent don't have some focal place they work from. Yea I've got my ship, but it's no office. I know it'd be a bit of an overhaul to rework the maps though, so again, it's just a want.
