Don't worry, your Rakata geared people will get all the Columi gear. I get gear off of every boss I've killed without fail. Do I already have something better? Sure do, but that doesn't matter. Do I already have that piece of gear? Yep. Still get it, though. Doesn't matter. Hey, at least my off-set is coming along nicely. I could probably out DPS the other people I've been running with since we started raiding if I decided to go DPS!
Please fix system, Bioware.
