I like the fact that there are a great many cool uniform options to wear. However, after you start obtaining armor, they become obsolete. I am not sure if there is a setting for it, but I would like the chosen uniform to always show and not the armor (also, not the kit either). It seems out of place to run around the starbases with the armor on.
I play Lord of the Rings Online as well, and LoTRO has a costume setting so you can turn on alternate costumes or even turn on/off the visibility of certain pieces of armor. This does not affect game play or even the stats that the underlying armor gives you, but it does allow you to really customize your characters.
