Mouse over macro issue

[ShiftingFate]

Hi All,

I play SCH and am a huge fan of mouse over casting. I set up my macro as follows:

/macroicon "Physics"
/ac "Physic" <mo>
/ac "Physic" <t>
/ac "Physic" <me>

So ideally this should cast Physics on my mouse over, if i don’t have a mouse over then it should cast it on my target, if my target isn’t friendly then it should cast it on me. Trouble is this macro all the time will sometimes IGNORE both my mouse over and target and hit me with the heal. This has been bad because sometimes that heal is a crucial one.

Does anyone know how i can improve this macro or even better can you just turn on mouse over casting in the UI somewhere?

Thanks everyone for any and all help.
