Hi, first, sorry about my bad english, hope you will understand what i want to propose...
There is too many weapons in game, you should change all wep durabilities to 1 use.
Now, with just one q7 factory, you can produce wep for 3-4 active players. If you change durability to 1, we will need to buy wep, and we will be forced to fight with other types of wep, not just q7, so other factories will make sense. It will be harder but more interesting, cause now isnt interesting at all...
