Soldier (Because who doesnt like more ammo pouches?)
Engie (yay, more places to put your metal)
Medic (For when one canister of syringes isnt enough)
Sniper (all thoes extra bullets gotta go somewhere)
Demoman (Why have 6 big granades when you can have 20 smaller ones)
Pyro (You can never have enough matches when some of your co-workers are chain smoking backstabbers)
