Popular RPG games in the past have been isometric for the simple fact that technology couldn't hack that kind of game in 3D person or even 1st...
There is no such thing as RPG's are supposed to be isometric. I'm personally not a fan of these kind of games in 1st person, but other than that, everything works. The more control over the camera the better.
And if you can shoot fireballs, why wouldn't you be able to jump around like a Shoalin master?
