Think I'll just generally agree with most of what Filth has said about things.
Hoping that all MMOs eventually go toward the F2P model, or at least B2P, while being fair with its marketplace elements. I don't perceive a conversion as a failure and there's honestly little reason to do it the other way around when the F2P version can have premium services that effectively mirror the sub model. Bad games will be bad because they're bad games. Sometimes that's the direct result of bugs. Others are a cheater's paradise. You'll get those that just kind of seem to float along with little direction, too, or maybe more accurately bank on PvP keeping things "random" or "fresh" for people in the long-term. I guess there are lots of ways to easily say a game fails, but my motto there is that if they're still playable, they're technically not dead.
Anyway, my biggest issues with XIV I've seen little to no promise of remedying, and that's in meaningful alternative progression. There's no singular "right" way to play an MMO, but it kind of seems like the industry norm to perpetuate such with raiding. Those that enjoy such things have a pretty robust market, but everyone else is either left feeling left out or just trying to be blissfully ignorant of the development disparity that goes on.
Oh well.
