I have both Sleep and Repose set up in Macros. (sorry if this isn't correct, trying to remember off the top of my head. But you get the idea. Also, remove the FA line for BLM...)
/micon "Sleep/Fluid Aura"
/ac "Fluid Arua" <t> <wait.1>
/mark "Bind 1" <t>
/ac "Sleep/Repose" <t>
/em is putting <t> to sleep, please do not attack! <wait.26>
/em looks worried, <t> is waking up!
(though I should change the last line to "sleeping enemy" instead of <t>...does make for some silly situations as a healer when the tank is "waking up" lol)
Now, I know BLM is AoE past 36 (or whatever), but when I AoE sleep during a fight (not speed-running) I just want the marked enemy saved for last; keeps things a little more "organized"
