Well, I guess different people have different priorities, the uniforms of Enterprise aren't even UFP Starfleet uniforms, they are from Earth Starfleet and hundreds of years old, while the AGT/Endgame uniforms are the ones that would canonically be used in the time STO is set in. And now that everybody is a high-ranking admiral, uniforms for all the existing sets would be great.
Not being from the Federation or the right time doesn't really matter, though. We have Mirror Universe uniforms which are a century old and from another dimensional plane :p
The reason I think they're the most important is because we have TOS, TNG, DS9 and VOY all being represented, so we should be going all the way and represent every show. But you're right about Admiral Uniforms, while I personally RP a Captain-rank player it's pretty odd seeing Rear Admirals running around in the same thing an Ensign would wear.
I'd like to see space suits in STO sooner or later, with all the dangerous planets we go to, surely not ALL of them have a totally breatheable atmosphere, would be nice to have like the Voyager/TNG film space suits or the enterprise ones as well
... What the hell is that? No, seriously, what the hell is that? Urgh, I can see it now. The next great Forum Blitz* is going to be 'Uniformgate.'
Sigh. Anyway, I shouldn't complain. I found the AGT/Endgame uniform to be ugly as sin. Uniforms I'd like to see are the ENT MACO uniform, the Picard Suede Jacket and the hazard suit (with helmet!) from ST Voyager: Elite Force. I would not mind seeing these in the C-Store.
Admiral (and Klingon) coats should be in the game, not the C-Store, as awards for getting some ridiculous number of accolades.
ETA: Okay, looking at it for a bit, it does sort of grow on me, and it's not *horrible*. Would be nice if that gold could be changed a bit. Still, it's not that bad. I actually kinda like it better than the Endgame uniform.
