BRD macro

[lumpenhund]

there is 2 kind of skills for every class:
GCD skills that trigger your Global Cool Down and oGCD (off Global Cool Down) skills that have longer reuse times and can be used inbetween GCD skills without pushing back the next use of a GCD skill.
The latter, oGCD skills, are finite in that matter, that you wont have one available for every time you could use one inbetween GCD skills.

oGCD skills for bards are e.g. Misery's End, Bloodletter, Repelling Shot, Blunt Arrow
GCD skills for bards include Straight Shot, Heavy Shot, both DoTs

So if your GCD skill is ready but you are using Bloodletter instead of a GCD skill, you wont be able to use Bloodletter inbetween two GCD skills, if you have no other oGCD skill available at the time, you just sit there and wait out the GCD, thus wasting the opportunity to have 1 GCD skill extra.

My previous post gave compared two skillchains of 3 GCD and 2 oGCD abilities used if you weave the ME and BL between HS.
You only achieve 2 GCD and 2 oGCD abilities in the same amount of time with your macro.
