Bishops & Auto HP?

I am a Bishop and YES I have auto hp &mp. I use Ginsengs on MP and Power Elixer on HP. I never have to buy Power Elixer since it drops from skeleton and after my training I always end up with more Power Elixer than when I started. I seriously dont know why people use manabull either. LoL Ginsengs are just cheaper for me so whenever i train i only have to buy ginsengs and my power are just always there from skeleton drops and pap drops. Plus i never have to heal. All i do is walk around and spam genesis all day and doesnt even have to worry about dying at all.

edit: I set my hp to about 40% and mp to about 50%.

edit: I always train with a hb mule.
