Will they maintain AP cost for native abilities?

So in this scenario it's simply UI's action bar that is the limiting factor. That may not be a bad thing. Plus the capability to use macros for skills that exceed the capacity of the action bars mitigates that limitation somewhat, I think.

I agree but from the developers point of view, I remember reading that the point of the action bar was to eliminate the need of macros for quick actions, as opposed to the drop-down menu from XI.

So I'm not sure if they would consider relying on macros for extra abilities. I'm not sure how they could fit so many abilities on the action bar and keep it efficient, considering that it was stated that there were plans to make all the actions slots visible at the same time, compared to the current toggle between 1,2 and 3.
