Lvl 55 DPS Sorc. I use Xalek in tank stance for the most part, Put a shield on him send him in and when the mobs get closer I hit them with chain lighting then lightning storm. If I have a nastier fight I'll use khem in the same way but if its going to be one of those pain in the butt mobs like Archon on makeb I'll pull out Talos to keep me healed up
