I think that purification should be turn on. It will make tao class more balanced to pvp, cuz now tao pvp crap, and than you dnt need to add new pet. It should work only for lower or same level that is owner of that skill is. What's more it's a basic skill for all taos on every server. What are you thinking about that?

tbh it should get fixed, would even out taos quite well.. that + xeno would make a tao lethal.
