I didn't know the first time I did that flashpoint...and I did it for the first time on Hard mode with a random group with the Group Finder. They had to teach me how to do it.
i guess i should have added that this fellow had over 700 presence, which would suggest that he's played through the game a few times on a few characters. so you'd think he would have played each FP at least once, unless he was like, pvp only. not to mention that he played as if he knew the FP. (presence was noted because we had to run the FP without a healer, as ours dropped out of the party before the FP started, so we were seeing who's healer companion would be most effective while we waited for another random to que.)
