I've made a few changes to Steady/Cobra Shot so it won't que it up for a cast during Global CoolDown.
Oh and you guys should set your Custom Lag Tolerance (In Interface > Combat) to something around 250-400. This allows for spells to que up before global cooldown is over, it should speed up the casting and thus DPS.
One other thing; Do you guys think Bestial Wrath should be used off cooldown on all targets? Then I could make sure that if BW is just about to come off cooldown, I would wait to use some spells (A Murder of Crows, Maybe Kill Command). Delaying those attacks for a few seconds to get the benefit of additional damage and saved focus should be more benefitial than losing on a few seconds, right?
Edit: Update is in the SVN now. Virmen's Bite included.
Edit2: Currently Virmen's bite is used on Boss asap as long as you don't already have it. I'm changing it so it's used if you have Bloodlust and Rapidfire and/or Bestial Wrath. Any thoughts or objections to that?
