Will the cosmetic armor/clothes that we use to cosmetically outfit our companions? eg: could I use heavy armor to outfit Mako?

Alas, you're completely right -- I should have submitted this for the current Q&A that's dealing with patch 1.3 Unfortunately the thread for submissions is closed now, but I hope we'll find out about this sooner rather than later.

... I mean, the ones that CAN show armor, that is. I realize that I won't be putting Qyzen into a Republic Officers Uniform anytime soon. It would be fun to have that uniform on Corso as Heavy, Risha as medium; you get the idea. But I would love to spread some Imperial Armor around the Fury's personnel, y'know?

Clickylink Thing to note here is that with 1.2, the two points put into Valiance would actually be in Preservation instead, which allows the two points into Egress. A support build with main DPS coming from Force in Balance and TK Throw, support coming from fully buffed (triple-traited) bubbles, and has an extra immediate Heal via Rejuvenate.

N-210 Fusion-X Saboteur

X-115 Heavy Sonic Carbine, in case anyone wanted to compare the two.

Just a note here that dual-spec availability will be coming Soon™ as per the latest Dev Q&A.

Well, I admit it wasn't love at first sight, but she's grown on me. I'm very fond of the old girl, now.

Hue to Chest announced in upcoming patch "Daniel Erickson: The new and vastly improved ‘Hue to Chest’ system launches with Game Update 1.2 and there are more customization and quality of life improvements along those lines hot on its heels." Skittles Warriors, rejoice!

Another couple we didn't have thus far (I think): R-100 Elite Marksman Carbine S-311 Fusion Saboteur (as requested, above)

Heck if I know -- I just nabbed them both off the GTN this morning. And yes, some of the Cunning-centric rifles are pretty sweet and very adaptable. There's a few in the OP at the moment.

Couple more, here. R-60 Elite Marksman Carbine X-12 Riot Carbine

You have a 5'5" blonde-haired, green-eyed hourglass bombshell of a pocket healer who also supplies interrupts, DPS and describes making love with your character as "Fantastic"... ... and you're seriously asking this question?

... Moira Quirk was born, raised and living in England for over forty years. Exactly what would you need to consider something "genuine"?
