Straight up refuses to work, no error messages that I saw. Perhaps linked to recent API changes?

Yea, I made a quick fix to remove the protected API usage, but haven't had time to look into it more. Is the range fader set to use class spells? what class are you?

It works on party frames when choosing the "helpful spells (40y)" option, however it's a different story altogether for target frame where if you are a class that doesn't have friendly abilities then it'll never properly fade it if you're targetting a friendly unit.

A new method needs to be devised to incorporate both class abilities+helpful spells options for it to properly work on classes such as DH

I'll add my notes here instead of making a new ticket?

I, too, have noticed this issue on several of my alts.

Specs with the problem (tested raids with emerald dream world boss groups):

Death Knight (Frost)
Demon Hunter (Vengeance)
Hunter (BM & Survival)
Warrior (Fury)

I have all classes except monk at lvl 70 to test with.

My raid settings are set to Class Abilities, my party settings are set to Helpful spells (40 yards). I can't remember why I set them up different between party and raids, though.

I hope this is helpful?
