Yup. Definitely lag. One or two point blank shotgun blasts usually can take me out in BD. The health regen perk can also counter the CQ shotgun. I most often get shutdown in bladedancer by focused fire from multiple targets, heavy weapons, and people backing up. I don't even use the super unless I know I'm capable of getting 4+ kills. I never go running around the map with it. I pop it when the other team is grouped. Some smart teams can shut me down with 2-0 kills with it. Dumb teams give me an easy merciless medal. I can say that a BD isn't invincible. If it gets a nerf I don't see anyone using it.
