The prefrontal cortex is the part of the brain that basically tells you "it may sound like a good idea now, but it actually isn't". This part of the brain can take up to 25 years to fully develop and it is one of the reasons why teenagers embark into reckless activities that should be obviously avoided by any adult.
Some people here have been bring up IQ scores and parents culpability as the cause for this, and while it is not completely wrong, ignoring the fact that kids should be treated differently isn't going to solve anything. You can't expect to have gambling, alcohol or drugs handed freely to under-age kids because they cause addiction even in adults, whose prefrontal cortex is fully developed.
We make the mistake of thinking that the brain is just a tool we use to take decisions but in truth the brain is all we are. Every though comes from a chemical reaction in it. If teenagers don't have the tools to deal with "gambling" as adults have, you can't blame them.
If a friend of yours started suffering from epileptic seizures and the authorities would take away his driving licence, the normal reaction of a human being is to think "It's right, he should not be allowed to drive because he might be a danger to others, but I am sorry for him", You don't feel satisfaction if he lost his licence because of a problem inside his brain.
On the voice chat part, (I hope I'm not remembering this wrong, if so I apologize) the technology will be some sort of game-integrated discord channel, to that extent they mentioned some sort of partnership with discord. Really intrigued on how that will technically work but I'm not too excited about the feature per-se since I'll be on the EU servers.
I have played both the original and one of the latest "illegal" iteration. I have to admit that the amount of socializing you can find on those servers makes the current wow feel sad. It brings back that feeling of "having to group with others to do it right", that's something that is missing from today's game selection, although not everyone is fond of it.
What I feel is not there anymore is the exploration, the unknown, the cool item you would not have expected. You can play on one of these servers and have fun leveling to 60, make friends and re-experience something nice, but when you hit cap it's all about BiS farming and doing it in the most efficient way. It is as if there is a crowd of players who constantly move from one of these servers to the next, only to see how fast they can level up, get their bis gear fro mdungeons and clear all raid content available.
I couldn't find the feeling I had in 2004 about end game dungeons.
