I highly doubt WoW is going to be better in this regard, considering Blizzard has access to pretty much any text chat in the game, it wouldn’t be out of left field to assume they might record the voice chats as well.
That is a scary thought, I dk, half the time trying to set up a chat is a battle for me.
They are recording your playing too and everything you do and say. They have been able to do it since Vanilla man. They can watch your gameplay from HQ. WoW has built in survey. They can also see what you do with your PC at same time.
You really did not know this? 
I dont even know how it works when did it come out, you should just be able to talk as soon as you get in a group and if you dont like it you can mute.
oh no they can see all the incel websites i go on whatever will i do
Yes they do. And all your fapality action as well.
As long as you have WoW or BNET open.
So better close them when you go to do sin boy. 
I use the Bnet voice a lot. I refused to give out any personal info, or use other services for voice/chat. I also don’t have any public social media.
It lets me talk to people I have met via WoW, forums, or Diablo while staying within the Blizzard infrastructure.
It works great from my point of view - for what I want to use it for. VERY easy to call/get calls and the quality for me is fine if they don’t have something set up oddly.
Yes, Blizzard could in theory police anything on their platforms - we agree to that. That is a benefit in my position because I want to keep people accountable and away from me.
I have used discord before, but only in very limited amounts and only to talk to CMs/Forum Support Reps for the MVP things - which was rare.
Better yet I would like it if it was like rust, as you got closer to someone they would be louder, So in theory someone could be all cheesed at you as you ride away and it gets less and less it would be great.
Only if those programs are interacting with Blizzard software. They do not monitor our browsing, scan our documents, etc.
Once I discovered Ventrilo back in BC I never touched the in-game voice chat again. It was terrible. Not saying the current one is as well, but I’m happy/comfortable using Discord at this time and have zero interest in switching.
Problem is that they took too long to add it after the disaster that was the original in-game voice chat.
Besides, I just don’t trust it to be stable. Considering how often this game has stability issues within nearly all other aspects, I can’t imagine the current voice chat is going to be anything close to good.
If you pay your monthly sub with your credit card they get your personal info and whereabouts. What are you hiding?
Of course they do. They also have my real name, address, and phone number on file. They actually have my dad’s number as my emergency contact on file. Unlike my Govt, Blizz has managed to not have that info stolen yet.
My point was that Blizz is not monitoring anyone’s browsing, personal documents etc. Your advice was a bit misleading.
What is monitored is the game files, game communications, commands/software that interacts with the game, all interactions in game or using Blizz software, etc. They legally can’t touch things unrelated.
Hes messing with you lol
But they do have access to your computer because we gave blizzard the permission to download content. So in that way they can at anytime do so.
My main problem with voice in WoW are two. 
One and first: I am not a native speaker, and voice communication, for me, is terrible. Yes, sorry to remind you that a few WoW players are from lesser countries. We dare to exist, still. How people can talk slowly and still remain bumblingly unintelligible is maddening. Sometimes I understand Japanese better than English. 
Two and next: I like picturing my companions as heroes. Hearing the 50 shades of nerdy is a sadomasochist exercise. And I don’t like SM, sorry (cowardly, I admit). Hope I am not banned for this.
Simple answer:
People are already used to Discord.
In-Game voice chat is perfectly serviceable and comparable to Discord in quality.
It’s also super convenient to not have to run a secondary program (ideally on a 2nd monitor).
But Discord got big first, so people stick to Discord because they’re already there.
If they did this (updated, good version of in-game voice) pre-Discord, it MIGHT have had a chance, since programs like Vent/Teamspeak required people to pay for their servers if they wanted more than a few people in them.
Vent beat Blizz to the punch, then other programs and now Discord are far more popular. If Blizz had decent voice chat from the start that would be good, but they did not and now people are used to other solutions.
The quality of the Blizz chat is actually good and it is very easy to use. Like I said, I use it a few times a week. I get why it is not popular though when everyone is used to something else.
With me I love to hear other people accents ,like spice it liven one the chat and yeah it does at time become a problem when people rush and not listen.
Vent was the “competition” back when they first tried in-game voice, and it failed because the in-game solution was poor.
I think in-game voice would have had a chance if similar programs were still king now, but they’re not, Discord is, which is free, so there’s no barrier to entry like with Vent/TS.
Personally, other than trying it out when it was new, I’ve only been in 1 group that used in-game voice for content. And it was VERY clear no one was used to using it. Almost every person who hopped in commented about never using it before. And this was mid Shadowlands lol.
I use the in-game chat every time I play with a friend. It works well enough except when it doesn’t. Then you get failed connects or random drops and time wasted reconnecting or logging out/in to fix it.
However the friend I play with has an old computer so running Discord and Wow at the same time is not possible.
I like the convenience of the Wow chat personally, it’s not hard to use. I like discord for discord things rather than use two programs of once, but I’ve done both.
