I'm not sure if this is how this works - but I used to do this in SWG, and asking in-game got me nowhere.. so here goes.
Just re-subbed to hang out with some friends that wanted to play through some of the class stories, and I remembered that I had some old cartel pack stuff from when I last subbed - the chest, boots, gloves, and pants of the Thana Vesh set among them.
Since the Havoc Squad set is up for direct sale at the moment, I assume the price is going to bottom out a bit so I'm also willing to trade for pieces of that set so I can finally force myself to play my Trooper and finish his story.
If interested, hit me up here, or drop me a message on Markë (the e is alt+137) on Imperial side. Thanks in advance!
