as WHM i use a macro to replace the different stone skills on my hotbar depending on my level sync.

the only actual battle commands i use with macros are ground aoe effects. i can actual place them faster with /ac "Asylum" <t> than placing them with hand, even with the queuing issue.

then every WHM should have a text macro to call for help when your mana is low, like: /p Manasong please <se.2> ^^
