Yes lower your haste by at least 3% more. Get the cast time of cobra shot as close to 1.66% everything over is pretty much a waste. Run Firelands and get the h cloak from the rock dude on the hill I forget his name. Also get the h rag neck. These fights are pretty easy now a day. Here is my hunter if you want a reference to full bis gear. I know i am a slacker and have no epic gemmed my gear but we have had this on farm/sale forever so you can epic gem yours for more dps, however ultraxion dps is very random.
