Ghillie suit is almost useless to wear, without some carrying space like the smaller backpack. 5x4 seems excessive inside a backpack. I would like to see it changed to be rolled like a smersh backpack is to the bottom of the bag. Almost like a sleeping bag or tent is rolled to the bottom of a mountain backpack.
I also agree that you should be still able to wear your backpack or a smaller version of it 20 slot or something. Food, ammo, guns, and clips are getting impossible to carry.
