I'm not a big fan of using macros for the sake of using abilities that you forget to use.
It sacrifices control for convenience. You don't necessarily want to use all of your abilities on cooldown like that, so why would you glue a bunch of abilities to your Heavy Swing? And what if you only want Thrill of Battle without Convalescence or vice versa?
Glueing abilities together is simply a substitute for executing your abilities in a more controlled fashion. It might not seem like a huge deal, but it puts you at a disadvantage, one way or another.
