I like the Kvostov. It's fun to use but it is lacking in PvP. The three fire modes don't have a good time to kill. It puts out less dps then the doctrine of passing and the grasp of malok. And I have yet to get a kill with the semi auto in PvP. I'd like to see a damage buff against guardians. And it would be awesome if you could switch fire modes without going into the menu. Like clicking a thumb stick or something.
