The sort of people that hog these are the sort that don't know how to use them, don't value them (will abandon them if the opportunity presents), and are not in contact with the rest of the team (meaning they do not defend where most needed).
Same I think should apply to the Ammo techie. So many people use these as personal taxis that having a two player requirement would prevent this. Yes it would be annoying for mortar squads and people that need them, but that's less annoying than never having it because Mr.RPG wants a private taxi full of ammo to camp an obscure bridge with.
The Insurgency game-mode is the most fun in my opinion but is riddled with inadequecies. Taking these steps would address some of these inadequacies.. Can you imagine it, someone at main saying 'pls join my squad so we can use techies' rather than just taking one and moving it to the hill near the enemy main to get toasted.
