Concept Class: Shape Shifter

Ok, here's my new idea for a profession. The Shape Shifter. (Working name.) It would be a class that has the ability to turn itself into another creature, animal etc. It would use up lots of energy to shapeshift, but in it's new form it would be very powerful. Depending on the power of the new shape, it would only be able to stay in that form as long as it's energy allowed. Its skills could be for example: Tiger, Dragon, Phoenix etc. with long recharge times.

g2g, this was sorta rushed sry.

You know you really really shouldnt have posted this if this was a rushed idea. I know this has been mentioned before in another thread as well.

Yeah there is a thread somewhere with the exact same type of idea.
