Woot, got my Misery's KDR to 1.02. Its a major milestone for me as I've always been a noob-shot hovering around 0.65 KDR before the PPC nerf. After replacing my Gauss Rifle with an AC/20, my KDR has gone up a ton (pun intended). The AC/20 is an uber weapon for killing mechs.
Edit: After several more matches, my Misery's KDR is 1.10
Edit (17-09-13): Misery's KDR is now 1.15
