But there are several other MMO's that are happy to disregard their own content save the hollowed "endgame" and only 14 that dosen't, why is it wrong that it dose things it's own way?
"MMO's are stagnant! They're all the same!"
*One MMO dares to do something different, that some people like and dislike like pretty much anything as nothing is perfect.*
"WHY AREN'T YOU LIKE EVERYTHING ELSE?! WHY BE DIFFERENT?!"
Honestly I never had a problem with ARR or the MSQ, I like the way it's set up. What I've never understood is why if I didn't I should demand a game change one of it's core identities, one of the things that most sets it apart because I don't like it.
It's one thing to suggest imporvements. "Trim some featch quests." "This class could use X" It's another thing when your 'improvement' is "I like this other game, stop being you and be this other game please"

If all I cared about is story in WoW, it is there I have the option but it's not the focus and I've got to go find it, read this quest, talk to this NPC do things in order myself, it won't hold my hand or make it easy for me, but it is there. Should I demand WoW add an unskip-able main story because I and people like me would enjoy it? No, the game gives me the option to find what story is has if I'm willing to put in the work, but that's not the kind of game WoW wants to be.
Those who have no interest in the story have options, there are boost, road to 70 and if they really don't care the skip potions.
14 is a Final Fantasy game and an MMO, that's what it wants to be, if you don't like that, fair enough but there are options for you to bypass the part you don't and you only have to do the MSQ once, if you can't even muster that or to use the tools available to go around it, then questioning if you're playing the right game is valid.

Yes, games are there to make money but they're also adhering to a vision, if every game just did everything every other game in it's genre did then most would die out, it's their differences that allow them to occupy the same space, trying to mindlessly copy everything WoW did how WoW did it is what killed most of the "WoW killers"
