Honestly...majority of my time now is spent looking at my timers to make sure astral stacks is on, how much time left on enochian. And then my attention also has to be mindful to dodge crap or when adds pop. Also add in some form of rotation that will eventually be broken by dodging or some mechanic
There's also times when I realize after I refresh Astral Stacks that I have a few seconds of Enochian, so I have to get back over into Umbral and cast a B4. Or when I hit Enochian before the timer even falls off, so it refreshes at a reduced time.

I kinda wish they would give us a longer timer on the stacks and when using Enochian, it just overwrites with a new 30 seconds. Right now, its a little stressful to play BLM. Seriously, that last boss in Neverreap. I can barely get any cast off without being flung or run over by the boss x_x
