I never touch <mo> macros, they feel flakey as anything, and make things more complicated for me. I also never use <t> macros. I have <me> through <8> cure2 macros for emergency "heal party member x", that I use occasionally (mostly only the <me> one), and the rest of the time I have my focus on the party list, and scroll through. I do have <tt> macros for damage dealing, but that is something I only use in dungeons I am already comfortable with due to running multiple times. My default target is the tank at all times, unless the tank isn't keeping hate, in which case I am probably on either myself or the bard (it is always a bard) who has hate and is taking damage, and then only until the tank can wrest his hate back from the offending party member.... Anyway. Anything else is asking for trouble.

The only macros I have been considering adding are ones to repose ignore1 and ignore2 marked target, for those times I am in a group without a BLM.
