That's a really poor explanation. As if other online competitive games don't rely on familiarizing players with maps, weapons and tactics. That's the whole purpose of games like this, his reasoning for leaving out voice chat is also hogwash and I hope that no one thinks otherwise.
No, this only strengthens my initial concern and protest over this decision; that's some fairly ridiculous rationalization right there imo.
Edit; think about it, he says that they wanted to slowly release content so players could develop and get to know the tactics of the various maps and weapons and then goes on to say that they left out voice chat because it is used for tactics and they don't want to "scare" the players. That's actually, objectively ridiculous and self-contradicting.
