I spent the better part of an hour today making macros to switch between my most used classes.. to change action bars, equipment, etc. When I finally went to test them, I was devastated that there seems to be a /wait 1 in between each and every command. I agree with the above comment about being able to change my abilities more quickly manually, especially since I've become accustomed to doing it that way already before I tried macros.

Having saved action bars would be excellent. I know it may not belong here but being able to remove or at least more easily move/manipulate the "basic ability" of each weapon would be great. It's really a task getting it out of the way sometimes.
