In v1.32 was silently added this little "multiplier = 3;" parameter to the "manual" firemode config entries of all the miniguns, which tricks players into thinking the miniguns are firing 3 times faster than before, while all it really does is <b>consume 3 ammo for each fired bullet</b>.
I think this is completely hypocritical toward the players, and it's definitely not in line with what someone would expect from a milsim game. Please restore minigun ammo consumption to its previous state, or increase the actual fire rate to match consumption.
