Don't ignore the complaints. Play the game yourself and see if you agree or not. The main reason these complaints exist is Square Enix completely ignoring them. People advising you to do the same are part of the reason why FFXIV is seeing a record number of players leaving.

You can still enjoy all the content up until Endwalker. The reason people are still here complaining is that the game was good to begin with. They wouldn’t have engaged with it if they never liked it.

The forums right now reflect the direction the game is heading. Dawntrail's MSQ had the worst reception of any expansion, and patch cycles are getting longer with each one of them. Players now have to wait almost five months for a new patch, only to get content that is either extremely predictable, disappointing, or both.

FFXIV has lost its ability to create fresh and fun content. Every new piece of content introduced since Shadowbringers has flopped: Island Sanctuary, Criterion Dungeons and Chaotic Raids. The successful content — like Field Operations, Savage, and Ultimate — has been recycled across multiple expansions, with SE struggling to even make them look different from their past versions.

There are also other major issues, like job homogenization and how SE handles third-party tools. The game has been running for years with high-latency players at a huge disadvantage, yet they are not allowed to use tools to fix it. There’s no built-in damage meter, and every discussion between the dev team and raiders feels like a childish argument, while SE turns a blind eye to the fact that players are using third-party meters anyway.
