It's stupid imho, if all but last boss drop Columi gear, then it should be able to be cleared with almost everyone in Tionese gear. People having problems on some bosses in almost full Rakata gear is just crazy. Sure make the places harder but for the love of god stop using gear check to do it.
Not only is it lazy on Bio's part, it's also no fun at all spending 3 hours as some have claimed, and alot of credits to clear a fp.
