My forms are added to all my other abilities on the action bar and the stance/form bar hidden via addons, same with warrior.
My forms don’t really share similar bindings though, so it’s not like Shift+1/2/3/4, they’re more like Shift+C, Shift+D, Shift+A lol. Most of the forms are taken care of with the associated skill via macro, so I rarely have to press the form-only binding, unless I’m power shifting.
