I don't think this community understands what the word OP is anymore. There is a difference between that and a little strong. OP means unmatched by anything else to the point where even a terrible player can use it and come out on the upper end of the scoreboard. None of these jump a player from consistently going like 4&9 to 12&8, that would be op. Like a Cod 4 m16, the permanent 1 burst unlocked at lvl. From this game only guns I'd ever truly call OP in their prime were Vex, Suros, Pocket Infinity, Thorn, TLW, and maybe Red Death.
