Well, there isn't a subforum for macros, I figured I'd post it here rather than clutter the general forums.

The MO command used for macros feels incomplete right now. It goes like this:

No mouseover, No unit targeted:
Error Message.

No mouseover, one unit targeted:
Error Message.

One target with mouseover:
Cast spell on mouseover regardless of target.

Well, I guess in the literal sense it works, but I feel it'd work alot better this way:

No mouseover, No unit targeted:
Cast spell on user.

No mouseover, one unit targeted:
Cast spell on target.

One target with mouseover:
Cast spell on mouseover regardless of target.

This is what I've always loved about mouseover. Rather than just a tool to reduce the time your input takes, it also helps healers to quickly switch targets between themselves, a specific targeted player and other units.

Not to mention that the error messages just seem silly.
