The poll should be "Besides MP40 what is the most OP class". Because anyone who says the MP40 is not the most OP is wrong. The fact you could run Jug and still have as much as damage as any other gun and also having like a 64 bullet clip...lol
The UMP wasn't OP. Sure you didn't have to use stopping power, but you lost to other smgs and literally every non-launcher secondary at close range and get beaten by ARs, LMGs, and snipers in middle and long range combat.
