When you can slide at lightning speed, jump, duck,dodge all over, and hit every crit shot at 5m all the way to 40m, it's too much. No other weapon has that much aim assist and bullet magnetism (maybe Jotunn). When players talk about ttk, they don't get it. You take Rose against Scalar Potential. Maybe on paper, the pulse has a faster ttk than the hand cannon, but the pulse does not have as much bullet magnetism as the hand cannon. So, using a pulse trying to hit a hunters head while he dodges and jumps all over the place is difficult. The hunter using Rose, Ace, Crimson, Igneous Hammer, etc... can move all over as fast as they can aim at the players mid section or waist (not the head) and is able to hit every crit with little effort is overwhelming for players that are average using non meta weapon. Same thing with Kvostov, way to much compared to non meta weapons. Yes, you can use any weapon you like, but unless you're a really good player, it will be frustrating, and you will probably be turned off from playing pvp, especially competitive.
