It's just not as accurate as golden gun. Seriously if a Titan throws a hammer jump up and you'll probably survive that one now he can get you with the next one that's true, but the fact that if enemies jump or shadestep away makes you lose a hammer then having 3-4 would suck. Golden gun is damn near instant and has better range. The only thing I would want is for a golden gun to be able to be able to one shot a Titan. So buff golden gun and leave the sunbreakers where they are.
