What would it take for us to get a proper macro system?

But there's no difference! There's no difference between me swapping bars with a macro when I turn on Deliverance or if I could code an if/then macro to use either ability based on stance. It's the same: I press X and the correct ability goes off.

There's a difference in how involved you can make the logic. You can do it for one thing (possibly two if you want to get really involved) by swapping bars around. You can basically do it for everything by having what amounts to a programming language in the macro system.
