I guess you know more than anyone else on the planet. Is it being psychic or do you have insider knowledge that nobody else does? Because as far as everyone else knows it was co-developed by Blizzard Entertainment and Vicarious Visions and published by Blizzard Entertainment. Which is a far cry from being made by someone else and then Blizzard bought them last minute. I'm also not sure what you're expecting from it? It's D2 with modern graphics that's all it's supposed to be? That's still a massive amount of work.
FFXIV hasn't taken over the market. Two very successful streamers make up the vast majority of FFXIV's viewing audience. If they're not streaming the viewer numbers for FFXIV are lower than WoW's by several thousand. Right at this moment of the 62k people in total watching FFXIV, 52k of them are watching Asmongold. If he wasn't streaming it would be far below WoW in terms of viewers. In terms of players, who knows? But if viewership is lower player base probably isn't doing much better. When that New World game actually gets released that will have massive viewership numbers for about a week or so and then drop off into obscurity as well. FFXIV and WoW are the kings of the genre, but don't confuse streamer hype with FFXIV taking over the market. There aren't really any indicators that it's the case or that it has anything to do with the lawsuit.
I can login to WoW Classic right now in an off peak hour for my region and both Shattrath and Orgrimmar are packed with people. I can login to retail to my high pop server and Org and Oribos are filled with people from my server. WoW is doing fine, FFXIV is doing fine.
