BS this is a level 43 Q. We where 2 level 48's, 1 level 49 and a level 43. And we still got beaten, even though we kited it around. So either change the "level" of the Q, or change that OP boss.

Ok I understand that this is a hard fight... but you guys should most certainly beat it. We were able to beat it with:

 

50 - Assassin Tank (a fresh 50 with no gear)

44 - Sniper DPS

43 - Sorceror DPS

50 - Companion Healer

 

The trick to the boss is, you HAVE to intterupt that nasty spell (I forgot what it's called) Drain something maybe? Anyway, you should be interrupting every single thing he casts. Rotate, communicate, and it turns an impossible battle into something doable.

 

Now the problem we had was that the quest itself was bugged. Only one of us could loot the boxes and the rest were crap outta luck.
