Practice. Specifically, learn to anticipate incoming damage - all fights are scripted and even auto attacks are mostly predictable. Pick a fight (Say Memoria Misera, for example), do it over and over and over and over - you'll learn the incoming damage patterns. Then it's just a matter of picking the right heal for it, and DPSing before and after that heal.

Having trouble?

Look up a WHM PoV video for the fight you're practicing. Note how they move for mechanics, note which heals they use and when. You don't need to memorize the entire fight at once, just focus on the parts you're learning.
