I really enjoy watching cs go tournaments, especially majors where the prize pool is insane and all the teams battle for who is the best team in the world!
I also get inspired from pro games by seeing their tactics, their team play and their decisions in the game.
Another good youtuber is BananaGaming, he makes a lot of tutorials and helpful tips on how to play CS:GO! You can also watch LongBarrel who is informative and can teach you how to play cs:go or different tactics to perform with your team!
My favorite team is definately Astralis and my favorite player is Kjaerbye. Astralis in my opinion has a great captain and the all the players have their individual roles and a lot of skill. I also like their Coach Zonic, a legend in css and cs 1.6!
Personally, I match up against cheaters every 2-3 games and that's really annoying. DMG's to LEM's are full with cheaters, thats why I am slowly playing CS:GO less and less...
I once smurfed in Silver 2, and I see why some people struggle to get out of silver, there are many cheaters smurfs e.t.c, I hastily upped it to GN 4 so I don't disturb the people at their rank level!
