Alright, MG36 isn't worth the unlock. I know. I play mainly support. MG36 Isn't accurate enough standing up to use in place of an assault rifle (standing up or crouching, anything but point blank.) It isn't that much more accurate or fast firing in the prone position short to medium/short range to offset the damage reduction. If you're using this weapon medium/long range (the only thing this gun is significantly better at) you'd do better with another kit.
That's just my opinion
