Just had a funny idea. What if you increase the speed, maybe 2x normal walk speed, but put it in the secondary weapon slot? Pressing M1 with the jackmammer out would start the 'taunt', making the engie move at double speed. Engie has absolutely *no* mobility-upgrade weapons(not counting tele). This might make engineer gameplay a bit more fun and fast-paced. Maybe it's not as good as the pistol, but a few tweaks can be made(ex. can carry one building while riding).
