Seriously, I don't even know where people get the idea that 7.0 is going to end or even partially end the game, it's not just one or two people, it's like the vocal minority of the playerbase but majority of the troll posters.
If you don't like the game at all, unironically save yourself the money and quit now, but by all metrics at this point this game is doing extremely well and growing. There's literally no point in waiting for 7.0 to destroy anything. Spoiler: they won't. Only reason to leave this game is if you genuinely dislike it, not anything wrong with the game itself.
Let me just spoil the ending for all of you: FF14 is going to continue doing amazingly well, growing, and Square Enix is going to continue putting out content at the cadence they've established in like 8.0 or 9.0 or something, continuing to please a growing playerbase.
CBU3 has like literally created one of the most popular MMORPGs on the market, each expansion iterating on the prior one with some lessons learned and some new experiments, that succeeded with the playerbase at large. They clearly know how. Given how they responded to the complaints about things such as the SB and ShB Relics, clearly they're open to feedback, too, iterating to try and find things that people like. So don't huff the doomium really, no need to wait for 7.0. It's already amazing.

Yes yes, just a reaction to https://forum.square-enix.com/ffxiv/...as-got-to-stop , but seriously, we don't need a new thread every other day about how the game is dead. The statistics don't agree with you. If you don't like the game, don't force yourself to play it, but constantly doomposting isn't doing anyone any favors. If you genuinely don't enjoy it - take a break or quit. It's unhealthy to force yourself to engage with something you genuinely don't enjoy.
If you enjoy things/the game, but have some issues with it, then by all means, offer constructive criticism. Actionable stuff that says what you dislike and why, what you like that you think it should be shifted more towards, and actual suggestions on how to address the stuff you don't like. But Doomposting is NOT constructive criticism.
Do what's healthy for you, but incessant posts about how the game is over (when all available metrics - EVEN the Steam data, as I've shown a couple times now - doesn't support that prognosis) is neither healthy nor productive. If you hate the game or its direction so much, you don't need to endlessly post your disagreement. No one does. And basing your premise off of rumors (as the OP did) isn't anywhere close to constructive criticism. It's gossip.
