To be honest, no one did anything to get this armor. it was GIVEN to you for free once you hit 50. I think the shells should be brought back...for a price. My idiot butt vendored mine when I got CM items..I regretted that the second RotHC came out and I could no longer get them. They were cool looking, and that is why I think most people want them back. And (correct me if I am wrong) but the classic comm gear = rakata? The gear looks similar if I remember right. So you do have that gear. the classic gear used to be the high end gear before the expac.
Are you talking about recruit gear? Tionese, Columni, and Rakata involved running HM FPs, and OPs.
