Generally speaking your better off just not queueing for LI HM. 99% of the pugs your gona get put with are clueless and probably undergeared for it. Better off forming a group first with people that know the fights and have the gear THEN queue for it so you get the daily.
I have pugged and 1 shotted the droid.
As long as everyone is geared and knows what their doing it can be done
