I'd suggest if you're looking for tips or strategies, don't look to the forums, there's none here. Finding guides or articles on other sites is the better approach.

There's so much complaining here for a few reasons.

Some people (a tiny, vocal minority) are politically misaligned with the values of the game and are soldiers in their little culture war. They typically make alt forum accounts to make their problems seem more common than they actually are, and respond to their own threads to constantly bump them to recency.

Other people (the majority who complain) are up to date with the game and have completed it to a level they're satisfied with, have gotten bored or burnt out but continue to login as if something new might have dropped overnight. They have a short memory so they frequently repeat the same complaints here over and over and continue to get more frustrated day after day.

The last group is mainly people who pop in, voice a complaint, then leave. Usually they don't check if there's already an existing thread for what they want to say, resulting in duplicate threads being created week after week (filled with comments from the second group who have gotten angrier since the last time they shared their opinion).

From where you currently are in the game you don't really need to be concerned with the complaints. You'd be better off playing at your own place and forming your own opinions on things like story quality and how all jobs feel at max level.
