As many of you might have noticed, Turn Evil now works on aberrations, surprisingly this actually has quite a bit of PvP relevance, against Priests in particular.
Turn Evil now works on:
Shadowfiend
Psyfiend
Mindbender
Fearing any of these creatures can give priests some massive grief, both damage and mana wise, so be sure to use it, and consider glyphing into Turn Evil against some priest comps. If anyone has noticed any other PvP creatures that it works on, please add them to this thread.
