Macros
Leap cursor macro:
Heroic Leap macro that saves you a few milliseconds not having to click an additional mouse click when pressed.
#showtooltip Heroic Leap
/cast [@cursor] Heroic Leap
Execute Mouseover macro
A simple macro, this can allow executing an off target without having to drop your main target. Slightly less useful for Arms than for Fury but still potentially useful in some cases.
#showtooltip execute
/cast [@mouseover, harm, nodead][harm,nodead] execute
Bladestorm Cancelaura
Ideally you never want to cancel Bladestorm but sometimes it is unavoidable if adds were to die before the Bladestorm is over. This macro will be useful in those situations.
/cancelaura Bladestorm
You can add this line into other abilities so as to take up less room on your action bars. An example would be:
#showtooltip Charge
/cast Charge
/cancelaura Bladestorm
