[TF2] the worst weapon for every slot

one of the amazing things about TF2 is the sheer amount of weapons you have to play round with. unique gimmicks and mechanics on specific weapons can help you make all kinds of strategies and playstyles however some weapons fall behind. weather their mechanic isn't worth the downsides or the weapon is simply underwhelming compared to it's competition some weapons simply aren't very good

however what is the worst weapon for a slot? what's the worst weapon for every slot of every class. and what would happen if I used the loadouts created using those picks for the worst weapons in the slot.

the is the question I wish to answer today
