They would have said if they removed anything wouldn't they? and the mass effect elevator glitch is kinda completely different in the fact that if you restart (turn off and back on) then its fixed you can do that in this case.
and yes this flashpoint maybe out dated but never the less its still content and should be given the same level (or at least some) of detail?
On another note i found the some "replacement" legs on both the imps and pubs fleet (imps in the kass comms vendor and the pubs is the taris comms vendor they both has give legs for the five sets the both the Black talon and The Esseles drop. now i say replacement loosely as i haven't seen any post/patch notes to indicate that that are replacement but they are are the right level range and as far as the helms go apparently they dropped in beta but don't now so i haven't got a clue whats happen to them i didn't play in beta i played when the game came out last year.
My point about the elevator glitch is only that it isn't unusual that glitches in BioWare games persists for multiple years. It is however far more likely they just removed it from the loot tables. I got no clue why they would remove it.
If it is removed I don't know why they haven't notified us, at least I don't recall them doing so.
