Coupon Exchange

I think that could decrease the numbers of coupons to exchange for weapons permanent.
Let me give an example now.
The m4a1 gold exchanged for 100 coupons.
With this decrease could replace the m4a1 gold for 70 coupons.

It is a suggestion.
In the name of almost every player in crossfire, lowering the number of coupons to exchange for weapons.

Thanks.
