Since I have Garuda on Obey, I macro'd Aereal Slash (the AOE one) to Bane so it triggers right afterward rather than going to waste when it's off CD waiting on me to trigger it next. Plus of all the skills you could tie Aereal Slash to, Bane makes the most sense to me since I only use it when there's enough mobs in close proximity to each other with sufficient health to be worth the expenditure. If I'm using bane to spread DOT's to sleeping/bound mobs without waking I have to swap to the regular version, but that's a rare enough situation it's worthwhile keeping the macro'd version on my main crossbar.
