one quick change to your macro, if i may:
/cast [target=focustarget, nodead, harm][]Lightning Bolt


sorry, that slipped my mind. its kinda a failsafe if your warrior dies.
basically, the macro goes like this:

if the focus target is not dead and harmful, cast lightning bolt, if not, the pass to next parameter. next parameter is empty, so it just returns as true. so if true is true, then cast lightning bolt.


for your question, is your #2 button on a round robbin? they should attack in sync unless you have more commands to your macro.
