A key component to this equation is being overlooked by you Hyrist. The reason why SE is scrapping all of these core components of their game is because they are all fundamentally flawed. While the transformation of XIV is being touted by you as unprecedented, you are forgetting that the failure was colossal enough to warrant it.
It may be true that one single game has never before made such an overhaul, but that only supports the point that never before has a company with as much experience as SE has, made a game so poorly that the changes were necessary to make in an effort to salvage it.
NCSoft would like to have a word with you on that. They've had far more MMO's under their belt with far more games that have had to go free to play. This is Squares second MMO and the first wasn't wildly successful in comparison to the field of MMOs. (Even though it is their most profitable game. )
The Compoent you mention hasn't been overlooked at all. And again you depict things in the worst possible light. You act as if modern MMO 'failures' aren't commonplace.
As a reminder as to the trend of the field of games, very view game companies make a concentrated effort to reboot their game entirely. Rather, they simply change their payment model in an effort to get the players who think "I don't want to pay a subscription for this" to get in and then fall victim to the habit of impulse buying additional perks/trinkets. Or, as others have mention, they try to slap a new coat of skins on the game to make it look flashier.
While the situation did warrant a client-remake. The fact that Square Enix decided to do just that instead of giving up is part that needs to be commended above all else. This is a move no one expected out of them and many turned around and said "Just shut it down, you can't hope to come back from this."
Many more companies did simply fold up, close their doors and move on.
Oh, and as far as remaking the game goes. That is already an accomplishment. It's in alpha stage and it will be released. The success of this accomplishment will be determined on a person to person basis, and again, I am doubtful that you and Rinsui will be pleased at the final product - though I am more than happy to be wrong if and when that turns out to be the case. But until then, just as you will 'wait and see' as far as AAR goes, so will I wait and see to see if your dispositions change.
A few "Nice Trailer, but..." comments aren't sufficient enough to change a year +'s worth of negativity.
