NOPE.
It may be OK for NA or single langauge servers, but EU would be a mess.
For comparsion - I started to play Paladins. Didn't even know it has a voice chat. In my first game some kid started to give us commands in very bad English. I had to mute him and some other kid who started to argue with him.
Next game, we just joined lobby and first thing I hear is one guy talking to his mom in some weird language and another guy listening to some kind of... "music" I guess .... so loud it was unbearable.
At that moment I turned off the voice chat, never ever had a problem. Everybody uses either chat or in-game voice commands and I never had a problem.
Also I am flame-free from toxic players who just HAVE TO tell you how bad you are, because obviously it helps :-D
So, thank you,
but NO.
Btw. you reminded me of this funny video:
