This fight may be easy if you use certain companions but definitely isn't with Scorpio -- my favorite companion. I got owned twice in a row as a lvl 49 with this companion. This guy does no damage to speak of if your at range but if a companion or yourself is up close, he does a LOT of damage. A tank companion won't be doing a lot of DPS and will get owned since they are up close. That leaves you without help and if one side can heal to full and you can't, you'll lose. I chose the healer companion, Dr. Lokin, for this fight and was able to do it. He interrupted with his carbonite CC enough along with whatever CC I had to complete this. I was spec'd full lethality. The elites in this zone are easy as this spec but this guy wasn't. A DPS companion would have probably made this fight easy if it was done from range. All of the advise on just using interrupts is worthless since if he wants to heal, he can keep doing it until your interrupts are on cooldown. You need to be doing burst damage in this fight if your companion isn't the DPS. Maybe the interrupt thing works better when your companion is the DPS.
