Mouseover cast doesn't work for heals

title says it all. mouseover casts for heals are not working for me. before prepatch, no matter what I had targeted, when I was moused over a friendly character, it would cast whatever spell I clicked on them (as long as it was a friendly spell). now everything just auto targets me unless I actually have my friendly target selected. has anyone figured out how to fix this?

yes, I have mouseover casting enabled

It was like this on the beta too. I think disabling auto self cast supposedly fixed it? Not sure.

but I also want auto self cast enabled

Try
#showtooltip
/cleartarget
/cast [@mouseover] SPELL_NAME
/targetlasttarget

where you replace SPELL_NAME with the spell’s name, as it appears in your spellbook.

Go to options > Combat under Gamplay and then enable Mouseover casts

Oh that is an option now? Cool

this is what we used to have to do, and I dont really want to have to create a macro for every spell because of a mistake in coding. everything worked perfectly in 9.2. its only the prepatch (and beta) where this was messed up
