I logged on today to do some dailies and some hunter decides to gank me. It turned into a pretty good fight, but when I tried to cast exorcism on her, I got an error message "Cannot cast that on players", or something to that effect.
Possible bug, or intended nerf? If it's a nerf, they sure didn't let it stay around too long :P
Just confused, because I didn't see it in the patch notes. You'd think a nerf would be there.
I later did arenas today and it's definately confirmed, you cannot cast exorcism on PVP targets for the time being. Maybe it was a nerf (I'm leaning towards this), or maybe just an unintended bug (possible, though I kind of doubt it).
