Yeah that annoyed me but once you've won 10 games that will stop happening.
Are you new to csgo all together or just the competative side?
Add me if want, im only silver 2 so will only be able to show you little bits but I find so far one of the most important thing is having a team with good comms so would be handy going into a game knowing at least one other player will call out.
I've got about 70 hours of CS:GO, but just started to play Competitively, I will certainly send you a friend request
