I suggest adding this idea, which is based of Urban Terror, to AoS.
When you join a server in Urban Terror, you 1st have to to choose 3 'perks' for yourself. These upgrades consist of: medkits (you can heal other people with it), extra ammo, amour, silencer (perhaps you can remove the tracers on the mini map with when you have this attachment, and make it hard-coded so people can't edit the sound file to make it louder), a laser sight, grenades and a flashbang. Furthermore, if you have 2 weapons in your inventory slot, you will only be allowed to choose 2 of these upgrades.
So what do you think about this? Discuss.
