I don't really care much for the gold camo. It's tacky in my opinion.
Also, in MW3, leveling up the guns was a good idea, but I don't like earning camos for leveling up your gun. I would rather it go back to the MW1&2 way where you had to get headshots to earn camos. It showed that you actually have accomplished something rather than just using the gun for 500 kills. With the Fall camo in MW2, it would usually take 1000+ kills before you got the required 250 headshots for the gun. It adds long term playability.
In terms of the 'sacred' camo that everyone wants to get... I would like to see custom camo at say...14th prestige.
To further explain:
prestige 0 - prestige 13
5 headshots: Woodland
15 headshots: Digital
30 headshots: Urban
75 headshots: Blue Tiger
150 headshots: Red Tiger
250 headshots: Fall
prestige 14-15
5 headshots: Woodland
15 headshots: Digital
30 headshots: Urban
75 headshots: Blue Tiger
150 headshots: Red Tiger
250 headshots: Fall
300 headshots: Custom Camo
And for anyone that tries to remark, "earning headshots leads to boosting! remember how bad it was in MW2?!" I say to you, they have added a very simple way to report boosters, and they will be punished if they get caught. The community shouldn't be let down because some people boost. And also, people boost regardless of if there are camos available for headshots.
