I was thinking it would be so much easier if there was an addOn that simplified macros... for example, say I want to have a string of code in a macro say "Cast this spell, then this one, and this one last on a specific target" (but written in code), that would make it so much easier, less button mashing, and being as fast as I can about it in raids and dungeons when healing... I am struggling to understand how to write a macro that will do this... that's why I am requesting an addOn that will do it. Could someone PLEASE make this? If it already exists, then could you point me in the right direction please? I would appreciate it.
