A question for that reviewer: has he ever, in his carpal-tunneled, Gatorade-laced miserable "hardcore gamer" existence, EVER lifted a real sledgehammer? A honest-to-God, small, 5kg (that's five kilos, because fuck imperial measurements) sledgehammer with a short handle? I have, and let me just say, after a dozen swings it feels three times heavier. And unwieldy. And you curse the grandchildren of that idiot who let the handle be intentionally short.
I'm all for things having their weight, balance and (un)usefulness. But then again, I do prefer camera that's locked to my back, because it hurts my brain less to calculate which WASD key should I press to face the opponent and swing sidearm at him. However, if free cam and space key for realignment is the way to go, I think I could live with that, provided that there *are* also 2 keys that allow player character to rotate clockwise and counter-clockwise (this would also be a great way to align your char with what you're looking/aiming at).
