There are a few problems here. One is dealing with the need of extra control commands. If we map the weaponnext/prev to zooming, then you are forced to use those commands on your wheel to make sense. Not everyone does, I script the hell out of my controls, for example. (I have Best Bullet, Best Explosive, Best Shotty, and Best Pistol button.) Second is you don't usually need the ability to control the zoom in GES. In N64, guards poked around being stupid a lot and you had a lot of mid-range combat. In GES, you can switch to a quality mid-range weapon faster than you can change your zoom depth. Also, from a balance standpoint, locking the zoom to max enforces Bishop to be a long-range hitter and a close-range pistol that gets better damage but cannot be spammed. Having a variable zoom makes it a railgun for all seasons.
