So many people believe or think that Voice chat would make all the toxicity feel worse or more "harassing" however I really can't help but think that most of the people would laugh their ***off the moment someone would be baby-raging on them with help of voice chat, just like it's super laughable in games that do have voice-chat. In Heroes of the Storm (a MOBA of all things, probably the most toxic type of game ever created) the devs were reluctant to implement voice chat. A large portion of the community didn't judge it a great idea either, but turns out it made matches better and less toxic because players who would run wild on their keyboard weren't so enthusiastic about flaming on voice chat. Last time I played I'd autojoin voice and turn chat off, save for warnings and pings. Started winning way more after that, games became more fun and less stressful too.
