one thousand hours and im still gold nova 3
As long as you enjoyed the hours it doesn't really matter
If you want to get better, try getting people to play with, it helps immensely.
If you can't you then you can try to spend alot of time on retake, pistol only and community deathmatch servers (official ones are trash compared to community)
Also take off dust-2 and practice other maps, you can catch quite alot of people out who don't understand how to play some of the lesser played maps
