Chaos wasn't in Beta. I guess you don't need to balance chaos. But yeah, I was a fairly decent player, despite not having the best gear due to not really playing the game often. What I'm really trying to say is that I found the game less than fun. To say a beta was unpolished would be retarded, but it honestly felt like there was so much else they should have done in all aspects...but just didn't.
Oh, and when you get a chance: N-Tec - 3 upgrade slots, fill it with +Fire Rate, +Ammo Capacity, and +Damage. You'll be an unstoppable killing machine at all ranges. Everyone will rage.
