Minigun If you've ever played R2DA since the 100th update you will notice a heavy change in the amount of people that use minigun, that's because of the M249.
INB4 M249 is nerfed into the ground
Disclaimer
Since the M249 was added, it changed R2DA in a way that it shouldn't. Before I get hate posts by 12 year old keyboard warriors who only use the M249 and can't accept that other people have opinions I want to make one thing clear: the M249 is overpowered, if you don't believe me then you should read what's below.
Why it needs a change
The M249 can do a total damage of 10,450 without any armor increasing the ammo capacity, if you were to wear a tactical vest it would increase the total damage to 15,675, keeping in mind that the Minigun can do a total of 19,500 damage. While it might be true that the Minigun does a DPS of 1,625 DPS. You might argue that the Minigun has a higher DPS but you only get 300 rounds of it and even then due to the minigun's bad accuracy you'd be around 15,000 total damage if you had good aim. Back to the M249, if you were to go up to the bulldozer armor you would be near indestructible. The total damage would be 20,900 and considering the health addition it gives you. Though it is true you can wear a bandolier to increase the capacity to 450 rounds and deal 29,250 damage in total, all that is negated by the accuracy and limited amount of ammo you can carry. The M249 has good accuracy so you'll likely hit every hit if you have good aim. One fact is that if you are wearing bulldozer armor, refill 4 times at the same ammo box and hit every shot you can deal a staggering 104,500 total damage, around 3x the amount a Minigun can deal with the bandolier, also around 5x the amount it can deal without a bandolier without the negated effects. I don't think there's anyway you can defend the M249 counting those statistics. It doesn't really matter about the high rank requirement, at rank 20 it only takes a few days to get to rank 25.
tl;dr M249 > Minigun
Stats Suggestion

If the M249 is nerfed to be these stats which I highly doubt, there will be less people using the M249 and more balanced compared to the weapons in R2DA now.
