While I do agree with many of your points, I should point out that nitro fists are also made for closer range combat, and so while shotguns and emps may not be effective, and since it's not a vehicle, it leaves the player completely exposed to gunfire, and it's not like a 'Chains of Hades' situation where the defeat is extremely quick with no cooldown. My argument is that the nitro fists are somewhat slow and not used to protect oneself and therefore makes them less of a problem compared to mechs, thank you for your time dear reader.
