in tf2c the sniper is in his unchanged glory, 25 shots, vanilla reload speed, ability to quickscope, a shitty dot that needs a wall to work, and there's a lack of tools that suppresses him, (dh + mini crits, guilliotine, scorch shot/detonator, medic xbow).
only "nerf" he has is the presence of a classic-esque tracer, and that's it.
for open fortress there's the railgun, the balancing factor of it was that you couldn't one-tap healthy and armored players with it, but in this fork there's headshots that triple the damage of it (80/240), add the fact that there's no armor to make use of (only overheal), 150 max hp and it's a gg.
