Completely un-true, I have orange moddable belt and a bracer on my Jedi Guardian, found the belt on Tatooine, and the bracers on Taris.

Being able to expedite the formation of a flashpoint group helps to off-set the costs of getting yourself stuck in a group where you have one or two people who are clueless, and causing the group to fail. Who wants to spend 20 to 45 mins searching for a group, only to get in and find out your guardian tank has been stacking wisdom and cunning? Simply drop group, and re-queue yourself. Right now that feeling is painful. Granted it pays to examine everyone beforehand but some people are still inept even if they appear to be geared properly. Also like another poster has said, sometimes it takes a while to find a group, which means essentially you're sitting doing nothing. That's not fun. At least with a LFG tool you can queue up and go do daily quests while you wait. I don't consider spamming trade chat or any other chat channel compelling game play. One other thing, this argument isn't just for level 50 players who want to do hard modes, this tool will be for people leveling up as well.
