My Suggestion: Give us a syntax for putting more than one target in a single line of a macro, so that it can be executed synchronously:

Code:
/ac "Cure" <mo> <tt> <t> <me>
or
Code:
/ac "Cure" <mo,tt,t,me>
Or some other variation, which would let us say "cast cure on MO if it exists, if not then TT, if not then T then finally default to ME" on one line of a macro.

Thanks for reading, I realize it's a nit picky request and I know there are other more pressing issues, but I do believe that adding this would greatly increase the quality of life for healers!
