I have some grade 7 and 8 crafting materials from the boxes from space missions... does biometric crystal alloy ever drop form the grade 7 box? and where do i get grade 7 or 8 patterns... are they only BoP in raids?

so agents and bounty hunters are not supposed to do directive 7... blah

My friend and I decided to try to two man the normal mode of Directive 7. We are both level 50, and have relatively good hear, and have well geared companions. He is an assassin tank and I am a mercenary healer. We are doing fine in the instance... able to go through things pretty well. At the first boss I kill my companion by not being able to micro manage his target switch while healing... we are fine... Then we get to the second boss... the Interrogator ... this boss you fight, and it then scans one person and summons a cyborg version of that person that you have to kill and then switch back to the boss. It scans me... i see a cyborg merc appear, we start killing it. 5 seconds later a sith warrior cyborg appears, and 5 seconds later, another... 5 seconds later another.... etc... we quickly get overwhelmed. We try it again, and the adds are spawning every 5 seconds or so... no way we can dps down the adds before the next one appears. We then think that maybe it is the companions that are bugging out the boss... so we try to kill it with only the tank and the healer ... the boss scans the tank, an assassin, and a sith inquisitor cyborg appears... we are able to kill that add and then switch to the boss... this is the way the fight is supposed to go... then the boss scans me... a cyborg bounty hunter appears... and 5 seconds later a sith warrior... 5 seconds later another sith warrior... 5 seconds later... etc... this is with just Sith Assassin and Mercenary... when the boss scans me, the merc, it makes one copy of me... then starts spitting out sith warriors like crazy... has this happened to anybody else?
