I'm not sure I agree with the balance of weapons. If all the weapons did the same damage, then why have all those weapons in the game? The only thing that would matter is how the weapon looks. But there does need to be a line drawn though. I mean, why have a weapon in which damage is
----- that big and one in which damage is
----------- that big. Unless the first has a high fire rate, you will most likely loose.
Taking away stopping power would be a good suggestion in my opinion. You could have all the weapns even, but stopping power would un-even them again. Sae goes with any perk that would alter the health, such as juggernaught.
Some of the killstreaks are pointless and all have their flaws, I agree with that. The attack helicopter might get 2 kills, where as the pavelow might get 20 kills.
A horde mode would be good too. Zombies were fun. If only they made more available maps to start with instead of having to pay for them.
