So this is the open I have been using on standard fights for BM as of pre 5.1!
-10 to -4: Misdirect and Hunters mark (If the boss is going to moved to a predetermined point in the room where you can place traps and not pull him put an Explosive Trap and a Snake Trap there!)
-2: Prepot, Precast Cobra Shot
0: Serpent Sting
1: Bestial Wrath, Kill Command
2: Lynx Rush
3: Dire Beast
4: Glaive Toss
5: Rapid Fire, (Racial), Stampede (If you want to try to maximize the up time of Stampede while your prepot is up move this step to before you cast Lynx Rush, both options in my opinion are optimal.)
6: Arcane Shot
7: Kill Command
8: Readiness
9: Kill Command (Delaying the readiness in this fashion lets you get off 3 Kill Commands during your first BW)
10: Dire Beast (I hold my 2nd Lynx Rush until I cast my 2nd BW because if I used it here BW would expire roughly 2 seconds before Lynx Rush ends.)
11: Glaive Toss
12: Cobra Shot (Forget your focus keep up that serpent sting! I don't know how much haste you all have but with CDs up I'm going to say this cast was about 1 second for the sake of simplicity.)
~13: Arcane Shot
~14: Bestial Wraith, Lynx Rush (My second Lynx Rush even with the delay here is still used with my prepot and my orc racial. My Raid also has back to back Stormlash totems so it will be up for this as well if your raid does the same!)
~15: Kill Command
~16: Arcane Shot
~17: Arcane Shot (If you popped RF at 2 pop it again here.)
~18: Cobra Shot
~19: Arcane Shot
~20: Arcane Shot
~21: Kill Command
In 5.1 with Lynx Rush being changed to a 15 second bleed (Assuming we still use it in 5.1), the 2nd Lynx Rush would have to be used 19 seconds after the 1st Lynx Rush was used. I will still want all my CDs up while the 2nd Lynx Rush Bleed is stacking so In order for that to remain the case the first lynx rush would have to be used on 2 and the 2nd BW would be delayed untill ~21 and the 2nd Lynx Rush would be used at ~22. I would love to hear some questions from you all and maybe some suggestions to help maybe further optimize my rotation. I hope my opener helped you a bit if you seem to be having trouble doing a lot of burst at the start of a fight!
