This is what I've been able to find on the internets thus far....
/mk “attack1″
/ac “Heavy Swing”
/ac “Tomahawk”
* If Ranged, it will mark using Tomahawk, if Close it will mark with Heavy Swing. Heavy Swing Priority so it won’t cast tomahawk after heavy swing if in melee range.
/macroicon "Overpower"
/ac "Bloodbath" <me>
/ac "Internal Release" <me>
/ac "Mercy Stroke" <t>
/ac "Overpower" <t>
This Optimizes healing received from OVerpower+ Convalesence. I manually put up Fracture to get healing from the DoT as well.
Lastly....
/macroicon "Foresight"
/ac "Foresight" <me>
/ac "Featherfoot" <me>
/ac "Awareness" <me>
This makes it much easier to stagger defensive buffs. Press/click first time, activates foresight. Press/click again, Featherfoot. Third time, Awareness. There may be situational uses for the defense cooldowns, for example boss mechanic where they engrage and start to crit you, you'd use awareness to negate it.... but for all other fights where you try to minimize overall damage.... it's a good macro.
With that said, I've scoured the internet and can't really find anymore... are there any you use that you'd like to share. All contributions are appreciated in advance.
