Yea, I like how he used the LFG as a positive thing, when most of the people who are interested in legacy specifically don't want cross realm features that destroy server communities.
You think Blizzard hasn't done any research on this? They almost certainly know more than anyone involved in this conversation, including those running Elysium and other private servers.
Well, clearly they don't view it as worth while enough at the moment to attempt to make a legacy branch of the game.
Which is understandable, that costs money. I think there is a greater population of the game that has never even played the original content, had to deal with the "struggles" and challenges of the vanilla and TBC, which is a reason why people go to private servers. A lot of it comes down to wanting the game to feel like an actual MMO and have a community, and I would argue cross-realm and all that stuff effectively shrunk the world to nothing and destroyed a lot of the allure of the game.
I know I would be interested in it, with a mix of modern QoL improvements, I would personally play it with some friends.
I think it's ridiculous that Blizzard just wants to snuff out the flames and pretend that there isn't some interest in it. Private servers have been around forever, they clearly aren't a legal threat in terms of their IP, and if the threat to their income was large enough then that in itself is a clue of an untapped market.
