Job Stances

[Reynhart]

You're idea is sound, but as it stands, changing stances doesn't change your button layout, so it would just make the button layout even worse.

They could fix that without using macros. After all, the pet bar changes depending on the creature you summon.
For WAR, you could "fuse" Fell Cleave and Inner Beast. At level 54, instead of learning Fell Cleave, you could have gained a trait that transforms Inner Beast into a 500 potency attack while in Deliverance.
