If I had to be a Harry Potter wizard, I would say no.
If I could be a Gandalf wizard, then yes.
I mean look at this, who wouldn't run away from this board with horrible crap like this? Gandalf doesn't even show off anything great as a wizard, his inner power comes from being a maiar. HP wizards a lot of great stuff, and if you're worried about saying things well train and become a great wizard like dumbledore or voldemort and you can use spells without incantations.
