One of them was T side Nuke and would wait outside silo until most of the other Ts were dead and would start shooting CTs through almost every wall. In casual there are a lot of high rank players who are only there to shit on players like you. But back ina Valve employee let slip that CS: Your ranking range becomes less certain over time between games, increasing in RD. Track your progression on a variety of training maps and see how much you improve over time. Players want to practice against those of their own level in an unranked ladder. All you need to worry about is that you're getting better and beating people that are better.
People want it, it won't be balance, but 10vs10 is not either but still fun.
CS:GO ranks, explained
But if I start a new account, I get placed with other new players untill the matchmaker realizes I'm a probably a smurf and puts me with better matched people. At least if you encounter a cheater in 5vs5 unranked you can leave. Nothing wrong with biding your time if unsure. If they wanted to play "unranked" 5v5 and still be competitive mind set. Don't be afraid of failing! I know when I started I played comp too soon and got ranked really low and it fucked me for a while, but with the rank shifts I think most new people get placed in silver anyways. Games aren't about winning for everyone.
