The way I see it is that a spell’s position on the bars isn’t really important. What’s important is what button it is bound to, so you can get to it easily.
And I believe that, in practice, people are happy with the setups they’re happy with. There is, no doubt, a “best” way to set up key mappings, but I also believe that most people would not be happy with that “best” way, So no judgment about your preferences.
Personally, I concentrate on the numbers 1-5, with 6 & 7 as reach buttons, combined with Ctrl, Alt, and Shift. And then a few letters and others. A really advanced player with really advanced bindings will be using letters all over the place. Too finicky for me!
I place all my frequent-rotation buttons on 1-6, my frequent-use non-rotation or short cooldown buttons on Ctrl-1 to Ctrl-7 if I can. Anything I may need to cast quickly, or movement abilities also goes on a key I can hit in a hurry.
I banish long-cooldown things like Battle Shout and Hearthstone to the furthest reaches, like a side bar. I’ll just click on them when I actually want them.
I see the usual 1 through 0 bindings on your Bar 1, but I don’t see any bindings for Bars 2 and 3.
Maybe you have those bound to keys, or mouse buttons, but it’s not showing. Or maybe you’re clicking them - again, I’m not being judgy here. Clicking works for lots of people. We all know it’s not optimal, but very few people really need optimal placement.
Further diclaimer: Warrior isn’t one of my main classes, so my understanding and recognition of Fury is very basic. I may not even be recognising the icons correctly.
So with all that out of the way, here’s what catches my eye:
I would have mapped Bar 2 keys to Ctrl-1, Ctrl-2, and so on. Or Alt-1, or Shift-1.
I agree with the position of your 1-4 as the bread and butter of Fury, but I would definitely have Rampage in there beside them too. You want to be able to react quickly to a Rampage proc.
I don’t recognize the icon you have on 5. My bad, I’m sure, but I can’t find it on Wowhead either.
I don’t see Victory Rush/Impending Victory at all? Mayve I just missed it?
I would definitely have Charge and Pummel on very handy keys I can react to/hit very quiickly.
