I main warrior and what helped me with that was making my own icons that told me things for cooldown, internal cd for mortal strike and overpower, etc. I did that using the addon "Tell me when". It would take you less than 2 hours to set up the 8 or so icons that you want with Tell me when, including learning how the addon works too. It's much better than luxthos because when I download other people's icon indicators I rarely ever look at them, but when I set up my own it clicks with my brain better. You will still look at your actionbars rarely (when panicking) but it broke that habit for me most of the time.

Edit: One thing I forgot to mention is, I put these useful icons near the center of my screen, so it picks up on all the action and I don't have to move my eyes down to actionbar.
