mg and lg were toned down because they were too powerfull/spamy
i dont know for certian how much damage they dealt but lets say mg and lg killed you in 1 second, so thats 300 damage in 1 sec. with the e5 switch you can make about 1000 damage in one second with no problem. so isnt that a little too powerfull? its kind of the same if you would have lg and mg deal 1000 damage in one second. thats 3 times more than the damage of the mg that was too powerfull.
