There's actually nothing *wrong* with the perspective used, only it's not the standard you'd see in every other isometric game, and if you played diablo 2 for so long I'd see where you'd find it a little bit odd.
Diablo 2 uses the standard isometric view of 45 degrees
Divinity, and beyond divinity use a more acute angle of around 65 or 70 degrees!
Nothing wrong with it at all, looks great. You'll get used to it...it's a great game.
Ps. there's a seperate divine divinity forum! <img src="/ubbthreads/images/graemlins/up.gif" alt="" />
