From TeamXbox: "Epic has done a lot of playtesting to better balance the buzzsaw with the gameplay. Now, it actually serves more as a last resort type weapon rather than something players rely on as a crutch or for an unfair advantage. For instance, if you have the buzzsaw out and just start running around like a fool, hoping to come up on someone and dice them up, you'll be quick to find this isn't going to work. It's very easy to shoot someone in the leg as they dash at you with the buzzsaw, causing them to tumble down, injuring themselves with the saw. Also, if they are using the "roady" run to run faster, this makes their head a prime target because of how the character sort of leans forward while dashing ahead. So there's a great balence in place that keeps one tactic or another from becoming unstoppable."
