A big logical fallacy that people keep spouting over and over in this topic is that FFXIV is losing a lot of subscribers because of it's current mechanics (which can be true) but that this wouldn't be happening if said FFXI/FFXIV 1.0 mechanics were in the game. Not only is this impossible to prove, I'd say that it's very unlikely to be true. We dealt with those mechanics 10 years ago because they were the only thing we knew. The world has moved on.
