Yeah sometimes we're on tense situations and we just "do I bene or noooooooooot ?????". I just prefer my sch partner telling me either something like "I got it" or "I do not have any lustrate up" rather than having to look at his buff among all his other buff each time I'm worried. Besides, sometimes Aetherflow is not up but it's going to be up a fraction second after you looked at it, so you would still loose your CD
