OMG! That gearset at 00:46 / 3:23 is awesome and I must have it. Where does it come from and which factions is it available for?
Kudos to whoever designed that one!!
If I'm looking at the same gear you are, going by the time mark 00:46 / 3:23, the Black and Gold gear is the Republic Trooper Black Hole gear. It's just Black and Gold instead of Blue and White which is what's available from the Black Hole Comms Vendor on Fleet. So really not any new design there, just a re-color.
Hope I'm wrong, but that's what I'm seeing at those time marks
