My 2 Cents. I use to make a new macro for every spell, like /assist focus /cast whatever. Now though i have one macro /focus party1 for one of the buttons and the second button is /assist focus so whoever is leader of my group is focus (so if one dies i promote the other) then i hit the assist button and then click whatever button i need. So it gets rid of the countless macros -.- hate macros lol
