I'm not sure how to open quite yet but what I'm doing is Raptor Strike (x4), Explosive Trap, Lacerate, Raptor Strike, (aspect of the eagle) Mongoose Bite x3, Raptor Strike (maintain buff), Snake Hunter and MBx3 again
Flanking Strike only if you cap focus, rotation wise using ET on CD, keeping lacerate up, keeping raptor strike buff up, and using mongoose bite when you have 3x or more.
This could be completely wrong, I don't have anything to base it off of. I'm using Way of the Mok'Nathal, Improved Traps, Snake Hunter, Serpent Sting, Expert Trapper.
