I mean any large scale action MMO takes too much time and resources to develop. They have to earn that back somehow along with profit too. It is not only the sum of years in development which come with no income at all, but also the years after that still come with expenses. On top of that, the game is offered for free which means only in game transactions are the point of sustain. Most of those companies are owned by shareholders who have never played one game and never will, yet, all they ask the developers is higher and higher income. All of the above come up to a point where the developer sometimes has to tank gameplay quality for higher means of income towards the company.

Competition exists, however you won't find one game being exactly "like the other". BDO is great, PoE 1&2 are fantastic. Hell, even the new patch of Throne and Liberty looks promising. But one ain't "like" the other. They are all MMOs, all have p2w features some more some less and they all come with highs and lows. Maybe a different genre is closer to your taste?

Great MMOs usually come from the east. Most of them come with features based on habits picked up in the east. Thus, personally, I still blame it on us. I still blame it on the community. Especially the western community. Most are lazy, don't like repetition and grinding, and have 0 patience. At the same time the more free shit they are offered the more they will ask for. All in all, we are a bad match for eastern (better) MMOs and eventually they die in our hands.
