When I get an Vassili loadout card, I don't even LOOK at the primary slot anymore - aside of REALLY small differences all sniper rifles feel the same.
Maybe make one semitautomatic? Or even fullauto? Give a better running speed? No idea how to fix that tbh (you are here for that
) but as it is, Vassili's loadout don't seem to difference between eachother over the primary at all.
