Swap out BW with Stampede. So 2- RF + Stampede. BW is off the GCD so it can easily be macro's into other abilities.
The issue I have with your macro is that... no matter what you do you can only press it so fast, and Macroing shots together is not an option. By pressing the macro, shots that normally wouldn't have a GCD and could be macro'd into other shots can't anymore.
Other than that issue, I think your macro looks fine.
Oh, BW should not have been there, meant stampede.
So, this should be better then?
2. MD + Pre pot
4. Stampede + Blood fury + RF
Should i maybe delay the second dire beast in the macro and swap it's place with the SrS? This way the SrS wont fall of for 1 sec but the DB will be used under BW where an arcane shot could have been used instead.
