i agree that FACES are very dark on KDF side, very often, and should be brighter, in particular in brightly lit rooms.
btw. whats up with the lighting on Qu'nos First City? When you walk into the Great Hall or the Bank area the whole map gets dark, sometimes when you walk out the bank it doesn't get bright again, and when you walk out the Great Hall it just flips from on to off, instead of a smooth transition.
The Shipyard in Space also has odd lighting when walking from the Transporter Room into the Shipyard...
The fleet starbase is dark. I just made a fleet, for myself and my alts, went to the starbase to see how it look, and it's dark.
KDF ships are dark, but it's canon. Unfortunately.
Also, more weather is always cool.
