I put the actions where it's important for me to see the cooldown timer on row 1 and the rest are macro'd so it doesn't really matter what order or what row they are on.
Like, for example... Featherfoot and Foresight I kinda have a feel for so I macro them (but I do also have /recast Featherfoot and /recast Foresight in those macros on the second line, just in case) but certain moves like Heavy Swing I want to use whenever it is up, pretty much immediately most of the time, I have it on my first bar. Reactionary abilities like Jarring Strike, Haymaker and Fracture for certain get the macro treatment since the cooldown on them hardly matters.
