Do we need the crouch ability in our game? (opens in new tab)

I've seen games that feature increased firing precision while crouched. The mechanic can lead to changes in pacing and ammunition spending. I personally like it. But why not just have Hold to Crouch as default? Players who set it to toggle will have forced awareness of the setting and the relevant button.

I don't think you can make a fps without crouch, might as well take away jump while your at it.
