About jumping again: Being able to jump is fine, but always doing a somersault when you jump is something I don't like, especially in full armour and with a giant weapon on your back. In SW: KotOR, you could do Jedi somersaults with full armour if you used the force, and it fitted into that game. I don't think it fits into a fantasy scenario, even less so if it isn't some special skill or spell. Okay, it wouldn't be a reason not to buy the game, but I'd consider it annoying if every character did this ... looks too much like a superhero or some Asian-style martial arts specialist in my eyes.
