Bullet Canister is OP man. Since reloading is turned off, even when it says the bullet canister is empty, I still shoot when using something like the burst triggers. So, if I were to take 5 burst and combine it with quad shot, it quickly becomes insanely overpowered. Now, take this and combine it with faster fire rate, and it becomes better. But drunken mag and grip make this better because it adds to the shot count. And finally, add the bullets that follow your curser as well as accuracy upgrades, if you switch them out for the drunken mag and grip, you can just hold your mouse in the middle of the screen and keep shooting, letting the bullets fill one area, and when it's enough, use them all to insta kill a boss. It may be less practical, but is more cool.
