I've read an AST 60 guide (as much as is applicable to a 50) and follow everything in it. Been grinding trials/dungeons for my poetics for days and the role (on WHM/AST) is not getting any easier. Even 50's dungeons are confusing and headache-inducing, but nothing phases me on DPS.

Other than not spamming the biggest heals, dodging, predicting damage when possible, not staying in cleric stance too long, and not running out of MP, what am I missing here?
