Quote from NandiniI've always used a bandage spell as my range check for non-healing classes. The range is 15 yards, but I'm not sure if that's any larger or smaller than the interact or follow distance.
What result do you get with Mend Pet (45 yard range) on a friendly unit other than your pet?
I tried mend pet - didn't work, unfortunately. Most likely the IsSpellInRange check returns null for an invalid target (you cannot case MendPet on your pet Paladin it seems; who'd o' thunk it? :))
