ok well basic rotation is hunter mark > serpent sting > Black arrow always on cooldown > explosive shot always on cooldown > Cobra shot to focus build > Arcane shot is your focus dump only when you got atleast 50 + focus remembering to keep focus ready to used explosive shot/ black arrow on cooldown and when the target is below 20% health using kill shot on cool down and whenver TnT procs use all procs on explosive shot
now adds is allot easier just Multi-shot whenver you have enough focus and using cobra shot to build focus no need to use hunters mark on adds
thats pretty much it hope it helps
