half the people who say that they would play on such a server want to show how good they are and how good they can use stock weapons. But admit it, unlocked weapons are generally better than stock weapons. Go and see in the statistics : less recoil, more damage, etc. There are a few exceptions (for example ak101 better than l85a1). The ones who say that the m16 is better than the g36e are clueless. G36E is way easier to use and way better, period. Now its your choice to have fun with the m16 and have a better challenge, and I understand, because thats what I want sometimes. I personnaly don't use the g36e because I like the feeling of the Ak, as I prefer flying with a joystick even though I'm better with a mouse. Also, as I often play on SF, G36E cant be used except if you are SAS.
I'd personnaly don't mind playing on a non-unlocks server, because everyone would be stuck with the same disadvantage, so it would be even.
