Just to be more clear, I am not talking about the actual abilities. I am talking about the icons you can choose to represent a macro that is the same icon as the actual ability.

I've have on more than a few occasions had to set up a macro that is basically the same as the actual ability, except that I wanted to add an additional command, hence the macro.

The problem is, using the macro even with the ability's represented icon from the selection, it doesn't give you the countdown of the skill, which defeats the purpose of knowing when the ability have cooled down.
