This. I tend to bind abilities in similar positions with similar effects. My Flash bind is the same for Unleash and Overpower. My combos are all basically the same keys for all jobs. Even my defensives line up on similar slots. Shift-6 is Hallowed/Holmgang/Living Dead. There are some exceptions, 2 is Shelltron/Inner Beast/Darkside. Darkside doesn't seem to fit, but it makes sense to my brain.
Having similar binds as you adjust to a new job and planning out space ahead of time while leveling helps so much when learning.
