Sup guys. I created a new youtube account for the sole purpose of learning the game. What are the GOAT channels to learn some stuff from? From fundamentals to specific agents, I'm just trynna get the best content to watch and not waste time...

I see a lot of people use blood effects so i searched up how to turn on blood effects and apparently its in the settings but nothing shows up for me just the normal settings no show blood option is it because i play in australia?
