I use macros on my bard, but no combined skills, as others have indicated. I have the basic song macros to notify teammates and other parties when playing foes, and the usual "stun" macro if I use blunt arrow, which is rare. But the main macro I use/have is my straight shot macro. Basically i have it set up to ping after 15 seconds so that I know to use the move again, and dont have to watch the icon on screen. This way the move is always up and I do my critical damage.
