That would be good to have this as an exotic...why not...keep the perk, but let it come at a cost. How about this, continuous shots decrease in damage. Like it needs a cool down. Then it won't be spammed as much, but we can quickly take out those pesky fallen walkers. Less time the better. We're still going to grind and play if you let us keep our cool stuff. That's why we play more...using our good gear. When you take it away, we lose our drive to play more. ..we still want everything, but forcing you to play with something else, will only lead to you punishing us for playing with something else. Take away special ammo and we use Ice Breaker. Nero shotguns and the we use fusion rifkes, nerd fusion rifles, now we use shotguns. Nerf auto rifles and shotguns, then we use hand cannons. Nerf hand cannons and we use the pulse rifles. It's this endless game that probably never needed weapon nerfs, just perk nerfs.
