A question about macroing abilities.

[Mibhas]

For melee, as long as you do it for your damage buffs and not attack actions, I'd say you can macro all buffs into one button for QoL.

I highly would suggest that you do not do this, since you'll probably delay your next GCD and you'd have to hope that your next buff will be available to go off in ~exactly a second (e.g. being animation locked). You can sometimes fit two in between GCDs, but you'll mostly only want to do one. Also, they have different cooldowns and you usually want to use them as soon as they come back up, rather than waiting for them all.
