need advice on Warrior for 51 - 60, dungeon leveling, macros, etc. with controller?

Okay, I'm getting the message loud and clear on the macros. So, I'm curious where you put your actions and how you weave them in to group pulls and bosses? If I was playing WoW with a mouse and keyboard like the old days (for me) I would have all my stuff on screen and it would be easy, but I feel space limited.

Then hook up a mouse and keyboard

If that isn't possible, find space. You have PLENTY of room on a controller, so figure out how to best set up your binds and get used to them.
There are TONS of console players who use a controller and raid at a high level

You have a 2.5 second GCD, plenty of time to switch between hotbars and back
