Alright so, I'm a troll and and an Engineer. Between those two, and flurry + (God forbid Heroism) I have enough haste that I'm spamming the hell out of the button.
I've tried mousewheel, and that didn't work
So I spam it's own button, with
/cast Bloodthirst
/cast Heroic Strike
/cast whirlwind
/cast Heroic Strike
But that's not enough.
So I'm left with getting Carpal Tunnel from spamming 1 and clicking 0. Anyone have a super secret macro syntax or addon that I don't know of?
