Can't tell you anything about your review because we can't reply
Beside that the 30Gb update is probably the legacy pack that you unlock after first launch if you had the first season, you could simply uncheck in the DLC tab the levels you didnt wanted to download

I can give my Bayonet Tiger Tooth ft for all of your csgo graffities and cases (Im collecting them) so if it's ok for you send me trade offer please. Link in my bio
