In macros, you can also combine multiple options, like:

/micon "Cure"
/ac "Cure" <t>
/ac "Cure" <tt>
/ac "Cure" <ft>

That would try casting Cure on your target, but if that isn't possible (like when you have an enemy targeted), then it would try casting it on your target's target.

You are wrong. Macros don't automatically default to self. The example given would try to cast cure on the Target then if that's not successful, it tries to cast cure on the Target of the Target, then if THAT isn't possible, then it tries to cast cure on the Focus Target. Unless you are targeting yourself or change the first /ac "Cure" <t> to /ac "Cure" <me> then it will not cast on yourself.

Sorry, but you're both wrong (I even tried the macro above just to make sure it wasn't something strange when doing as a macro!).

Cure (and Physick etc) will always cast on yourself if they cannot cast on the target in question. This has always been the case since at least 2.0 (possibly earlier than that, but I can't remember). If you have an enemy targetted or something that is valid to receive the cure (someone who just died or just raised for example), the cure will still cast, but will always land on yourself.

You can literally confirm this by finding any mob in the world, target it and just running the first line, /ac "Cure" <t>. From what you both wrote it should error, but it won't, it'll cast on yourself without an error (and in the macro it would cause the following lines to not run as you're already casting)
