To add on to what was already said, one thing that helped me specifically for AST was changing my UI around.

My left side of the screen is cluttered to the seventh hell and back to a lot of people, but it helps me do my job: I can see the map, hp bars, buffs, timers on said buffs, and all my abilities in one spot instead of looking all over for it.

I even had an entire hotbar dedicated to the cards and when Divination/Sleeve Draw was on/off CD.

I doubt anyone needs my set up, but changing your UI to suit your needs helps alot.
