I checked out some of the weapons. Most of them are really good, especially the MG4 and G36k EOTech.
But I think that the ROF of the MG3 is too low. It looks like it has the same ROF as the MG4. Which would be incorrect. The ROF of the MG4 is around 850 rpm, while the ROF of the MG3 is nearly 1200 rpm.
The recoil is also a little bit weak.
Also i would like to hear a more "aggressive" sound when firing the MG3, like it can be seen (heard) on many youtube videos... :D
Just my 2 cents :)
