@ octavian, I use 2 action bars with stances and pages set from other action bars with bongos.
My first action bar is the one i keep visible and have set to battle stance. I have then set action bar 2 as defensive stance and have paged it appropriately. The third is done similarly as are my stance dependent abilities with action bars 6,7, and 8.
Here are some screenshots to illustrate.

Hopefully this makes sense and is applicable.
