Still losing tons of credits for replacing the mods for minor upgrade, because Black Hole gear does not have the set bonus. Damn stupid design that you lose set bonus with a higher tier gear. I guess their testers do not have to depend on the set bonus because they just skipped BH and go straight into Campaign in their testing.
You are mistaken here. Black hole isn't supposed to be a set in between Rakata and Campaign, it's supposed to be a set of gear obtainable for people who don't raid all the time. Campaign is the first set after Rakata.
