Help with a Beast Master Macro

[halabar]

Also trying this adapted from the lazymacro site, but dps seems a bit low, but everything appears to be firing.

/startattack
/castsequence reset=target/3 Serpent Sting,null
/castsequence reset=5 Kill Command,Arcane Shot,Cobra Shot,Cobra Shot,Kill Command,Glaive Toss,Arcane Shot,Arcane Shot,Cobra Shot,Kill Command,Arcane Shot,Cobra Shot,Cobra Shot,Kill Command,Glaive Toss,Arcane Shot,Fervor,Focus Fire
/cast Blink Strike
/cast [combat]Rapid Fire
/cast [combat]Bestial Wrath

Any ideas? (Stampede and readiness are manual)
