I feel like out of all the regions I've played in, NA ranked was the best experience. My ping didn't allow me to do much (130 ping) but Silver players were comming a lot, they were trying to build their own strategies and actually playing as a team. I've never been called slurs too. EMEA ranked (Poland was where people were talking more) was fine, some people were screaming on the mic for no reason lol but it was fun, there was also a lot of players asking me if I spoke Russian or Polish and asking me to teach them words in Portuguese.
Brazilian ranked is absolute hell, we lose one pistol round and people start screaming and talking shit for absolutely no reason (5 AM btw), lots of slurs being thrown around, no comms, everyone just does whatever they want to do. Wouldn't wish that on my worst enemy.
Idk if you Americans like NA ranked, but y'all should be proud of what you have
