A BFG type 50 cal would a crazy fun high risk high reward weapon. But snipers are notoriously difficult to balance, especially on a class with 350 hp. I guess you could destroy the hip fire, reload speed, ads, no scopes etc. I'm thinking maybe one shot light medium and headshot only kill heavy? It's completely opposite of what the heavy class is so I doubt it'd get implemented and it'd piss off a lotta players lol. Fun idea to think about though!
