Tried several strats and the one that works best is this:
Get an enchanter and dire charm a lvl 110 Cliff Golem;
if you tank goes easy on taunting, the charm Golem should take most damage and effects. The Golem usually goes down to around 10% with a group DPS output of 120K, which is the overall DPS you need to kill Needle.
Overall dont over-dps the mob. DPS control is they key. Once he summons, esp as a caster, you;re done for. Almost 200K unbuffed and still die within an instance. Needle casts a spell that makes you fizzle a LOT. Just hang in there and keep clicking, there will come a moment, that it will land. The fizzle debuff is cast on individuals and not the entire group.
But again, DPS control is the key for this encounter, so make sure all individuals do not overaggro (Needle targets you when >85% aggro).
As an alternative the Mage's Earth pet will work (with Fortify Companion and less mage dps due to healing). When you have a decent tank you should be ok as well. (dont have a real tank in my team, so wouldnt know the specifics).
Hope this helps
