Anzer, friends don't let friends us Macros.

Pretty much this. The only actions you should ever Macro together are cooldowns that need to be used together for maximum efficacy (e.g. For Paladins, Fight or Flight with Bloodbath, Awareness with Bulwark, etc.). And even then, it can be to your detriment to use a macro instead of just opening that third action bar, because it requires mashing a single button until it's applied, which can delay you for a few seconds until it's ready.

The target marking macros I posted are ONLY to be used for rapid marking of targets, and I only use them because they don't have consequences if something goes awry (if it fails, just wing it). You generally don't want to put your rotations on a macro, because the macro will break if you need to use something else while it's running, and then you won't have access to your combo finishers.

EDIT: Also, macros that call out actions that require others to participate are okay: so Living Dead, Divine Veil, Convalescence, etc.
