Well, I looked at what you had in list for the weapons, I was thinking maybe you could do two things that would really improve this pack.
First off, I looked at the equipment list, it does mention a good amount of grenades, I love it already, but I saw there was no sticky grenade, I mean; yea it's not everyones main idea to add to a weapon pack, but wouldn't you want to have a spare grenade to toss onto a wall, or just so you don't have a mad grenade bouncing everywhere? So lets say you got one, kinda reminds me of Bad Company where you hold it, throw it and the 3 second timer goes off with the light, sticks, if it doesn't it blows up anyways. If this was added it would be a very good addition to the weapon pack..
Lastly, I was looking at the snipers you have, they're all bolt-action, maybe you could add one or two semi-auto snipers, or maybe; an automatic sniper? I can figure you did bolt actions because of it being over powered if it's semi auto, you can always make the fire rate smaller, or the damage smaller depending on the gun.
I hope this is a good enough description of what I would like to see in your pack, hey; I love it already, can't wait to see the other weapons you have not finished yet, hope they look great, and hope you take this into consideration.
