I'm not sure if you still read or update this. But if you do, you should consider adding (somewhere near the beginning) something about how the GCD prevents one from using more than one ability at a time that share the GCD etc. Just today alone, I've seen several threads asking something about making a macro in such a way. Granted, I'm sure most of those posters never even bothered to read a sticky first anyway. But hey, every little bit helps I guess.
here you go

WoW macros are designed to assist your gameplay not automate it
@valenora I just havent had enough time on WoW past week to try out your macro and see what's wrong. Might be the entire macro is being cast at your focus target with those conditionals as they are dunno. Just delete the MD part and I do not see why it wouldnt work, but you shouldnt use a macro for all that unless there is like a very good reason why you cannot press the abilities separately.
