If FFXIV can be saved, anything can be. Saying otherwise is complete bullshit. The real question is will they put in the effort the fans deserve for putting up with their shit the past few month to fixing the game, and the answer is likely no because Bethesda has no integrity at all. Keep in mind that most of their games ship broken and stay that way until modders fix it.
As one of the actual people that played and enjoyed Fallout 76 without being just another bandwagon hater, the game needs to straight up be nuked like FFXIV and started over. If Bethesda had any tact at all, they would refund people at least a portion of what they paid for the busted ass game. The sad fact is Bethesda will continue doing nothing, insulting the people that still play the game with their worthless, joke patches. The majority of the gaming media will mostly ignore the situation unless they can get easy clicks instead of putting pressure on them to set things right. Bethesda should he getting railed as hard as they were since day 1 instead of getting away with this like they did with Skyrim on the PS3, which wasn't even remotely as bad as this game.
