What @ll_R_E_D_l is getting at, is that there is a clear distinction between “noobs” and rubbish players. “Noob” being a shortening of “newbie” - i.e.: someone who is new to something.
Players who have been playing this for ages can still suck.
We were all noobs at some point. Some people get better, others don’t so much.
I think what we have here, is usage of the term “noob” as some sort of a generalised insult.
