So 3 things I'd like to see:
1. A STVI The Undiscovered Country Klingon Uniform Pack (put in the Zen Store and you'll probably make big bucks; stuff like Gorkon's uniform, Chang's uniform)
2. Modify the Wrath of Khan Admiral's uniform so that we can change the rank pins to match our ranks
3. More cloaks/capes for the Klingons (the Vice Admiral gets a full coat, the Lieutenant General's just get a new baldric; we've seen the cloaks with the holoemitter in the Doomsday Machine mission)
"That hurts worse than the uniform." - Dr. McCoy on the Vulcan salute
"On Vulcan, the teddy bears are alive. And they have six-inch fangs." - Spock on sehlats
I would love to see the ability to have major accommodations be worn on the uniforms and even design some special dress uniforms. You could set it up so that you have to pay zen to unlock the feature. Thereafter major event accommodations and the hardest accolades could be added to the uniform instead of buying that generic splotch that doesn't look good. ...it would also give the players pride to show off their dress uniforms instead of wearing the combat gear everywhere as most do now.
