The point of Adapted is allowing Klingon characters to get access to the MACO sets and of Starfleet characters to get access to the Honor Guard sets.
Having a "Advanced Omega" would be what exactly? I am NOT paying a crapload of Dilithium, 30 BNPs and 1500/3000 OMs (skipping the EC costs) so then I can get a better set, MACO, Omega and HG are the end game sets, not being a setting stone for a even better end game set that would then be by its very definition the end game set.
you still need the optionals in the ground and space stfs to get the extra costume pieces, like the harvester chest/boots/shoulders for omega.
unless you just use the armor itself for the visuals, but you cant color/customize the look
Oh but what about the titles that the costumes replaced? Cause I remember there was like Omega Force Commander, Omega Force Squad Leader or something like that. Similar to MACO titles that are still available to unlock.
