All of the “I Quit” posts usually say something like “I have had it. Uninstalled the Game and going to play “XYZ” game, because its better.”
Like uninstalling WoW is anything other than a minor inconvenience. It can just as easily be re-installed. And in most cases, a fresh install, would be good for their game.
When I see the “Uninstall” Quitting posts, I just read it as, “I just put an hour of time barrier between myself and playing WoW again.”
because they want to imply that THEY MEAN IT 
They should put in for perma-delete of their account if they’re serious about never playing again. Of course they actually could still play but they’d have to make a new account and buy the game again and start all over from scratch LOL.
And then half the time they show up on the forums the next day
The same people making uninstall/quitting posts probably also posted what they had for breakfast on their Facebook wall a decade ago.
Right? Real ones throw their whole damn PC out the window.
Look, JAN, my omelettes are flawless and you should thank me for the privilege of seeing them.
My guess is if it isn’t installed they won’t be tempted to play it.
It’s like cookies. If you don’t buy them / have them in the house, you aren’t tempted to eat them.
I believe it’s sunk cost fallacy. People feel so invested in their characters over the years they’ve payed a sub to play them that uninstalling feels more significant
I just imagine a toddler stopping his foot, crossing his arms, and saying “I MEAN IT!”
I’ve uninstalled and reinstalled a few times. Some for reasons such as quitting WoW and others because I got a new computer to play it on.
Maybe that’s what they mean. They’re uninstalling off their OLD computer and reinstalling it on their NEW computer.
I don’t know, why do people assume people never quit?
Agreed, most people that quit don’t come to the forums and talk about it. And there’s probably a lot of people that say they’re quitting but are just expressing frustration with the game. But the games had over 110 million subscribers over it’s life span. And I don’t think we currently have 110 million subscribers, so one or two of them have actually left.
I don’t think anyone assumes that. But anyone posting about it here, especially without any actual feedback or complaints beyond “g4m3 sUx” is probably just looking for attention and probably isn’t going anywhere.
It would be permanent for me 'cause my internet is slow so redownloading all those gigs is one giant head ache 
But you can always ignore i quit threads… some uninstall as a sign of frustrationn… some actually have it be permanent and never return… lots have done it and never made threads on here about it… maybe if we perked up a bit, people would maybe less angry or make complaint threads about others complaining.
And one thing that’s completely counter productive in this situation is telling someone they have no reason to be upset. That can push them from expressing frustration to actually quitting.
If you actually QUIT, you will delete all your characters before you uninstall, otherwise you will always be back, and it’s just a break.
When I brushed my teeth last night, I looked at my toothbrush and said “That’s it. I’m DONE with you.”
And my toothbrush was like “If you were really done with me, you wouldn’t just put me back in that little holder on the sink next to that diffuser thing. You’d throw me in the garbage. You know you’ll be back, Dan, same time tomorrow, admit it.”
And I was like “Well played, toothbrush.”
Telling us how great FFXIV is, instead of just playing it.
