Ok, slightly off topic regarding skipping bosses but a tie in with bad behavior in flashpoints in general:
As of late it seems that lower level players love to need on thing that YOUR character needs and they have absolutely no use for. A couple weeks ago I was running Athiss on my marauder had a sorcerer need on a single hand strength light saber off the final boss. Today while running Hammer Station on my bounty hunter, I had another sorcerer need on a heavy helm with aim on it off the final boss. Both items were upgrades for the toons I was running with and neither of the players who snagged the items responded when I asked them why they needed on the respective items.
Needless to say both of these clowns went on my ignore lists on each of those toons. Knowing what most of you probably already know about what your companions can/can't use or even when you pick them up, why the hell are people being this stupid or being blatant jerks about what they need on?
