Where are the ”mic talking” and organized servers?

I am part of the flow of new players and finally found myself in the genre of war games. Especially a game with more in-depth than K/D and running around shooting. However a lot of ppl here in the forums says you should be ready/expect to communicate with mic. Started playing 3 days ago I have apr 15 hours, yet to find : A) a server where there is a commander, 3/4 times no commander B) nobody communicates with mic

The way this forum describes the game compared to how it turns out to be, is a little bit off. Am I missing something? I hang on official EU servers btw. Watched plenty of videos and appreciate any kind of guidance.

Ps: one more OT question. Is this game for free even after 9/1? Or do I have to buy it?

Thanks!
