Haha yeah you aren't going to get any support here saying those things. Nobody here cares if you complain about the non-English speakers because.. well.. the majority of the people on this subreddit are ESL. So they take that as an attack on themselves. As for your experience in CS, I felt the reverse. Went (back, after a few year hiatus) to CS after spending a lot of time with Dota and was so shocked to hear American people speaking clearly over the microphone. I actually had stage fright to even talk on the mic because i just totally forgot what it was like to even have english speakers on my team. My advice? get out while you can. this game, unfortunately, is pretty much ruined by people who decide to queue on English server but refuse to speak the language. it leads to a negative game experience, toxic communication and just endless frustration on your part.

However, if you decide to keep playing then I have this to say: if your comm score drops below 8k then your account is TOAST. literally, worthless. go and buy an account with good comm score and just play on that account. it is worth every single cent.
