Teammates not writing English = instant loss?

Hey guys, I experienced this so much but I want to know if somebody else thinks the same.

(This is on EUW)
When teammates start writing in any non-English language, they tend to be feeding, trolling or eventually afking. Especially French, German and Spanish players seem to be like that. It gets even more ridiculous when they start insulting you in their native language. I don't get it. If you really want to insult somebody, make sure they understand. Besides that, not writing English is a team communication killer. Give me any good reason, why it should be okay to write non-English in ranked games.

There is not much you can do besides muting and playing ur game.

I think the reason of defeat it's not the language that the players speaks lol

just mute them and focus on yourself xD ..........

It doesnt matter if your teammates writing not english, I had many games which my teammates wrote hungary or korean too, just keep writing english and ignore what they write in there language...they wanna win so they will understand your english, try to be the shotcaller and be the carry if you wanna win

Its really not, you might just have had a few unlucky games with non english speakers, someones language does not change their skill

As other people said, you just have to ignore them and focus on yourself, of course you can argue with them however people don't have to speak english...

This may be the most unintelligent post i've seen on here yet.

Haha! Totally, language doesn't equal a loss, sure a language barrier can be more difficult to organize a team, but trust me it's not like NA players work together anyway.

You can always use pings, and be annoying with them. From my experience eventually they follow pings in the end.
Or think smart ping the opposite thing you want them to do it worked sometimes xD.
