Theres no need to reset the stats though is the thing, no one can see your profile but you, there's no leadboard or ladder to try and get your name on (it would just be filled with hacks/cheats anyway like every other fps leaderboard), no one cares if you have a 4.0 k/d ratio or a .1 k/d ratio, or 10,000 kills.
Theres no reason to erase some peoples hours of game time for class levels, and vanity weapon unlocks just to appease some modern warfare k/d ratio fanboys.
"People want a reset after a fix is released so everyone has a fair and equal chance at leveling up at the same rate. "
The unlocks apart from the bayonet (i guess), and the bonuses do not give some crazy advantages, even at the higher levels, im almost to highly decorated with rifleman class its not that big of a difference really.
If your losing/dieing and going '"i only lost/died because that guy has a higher class/weapon level than me" you're probably the same type that thinks you only died in modern warfare/bf because someone unlocked the the games "OP" gun before you and you should honestly just quit playing fps' altogether.
