I don't think anyone would disagree FFXIV could be worse, but it also could be a lot better as well. Who is going to post feedback on the forums on how to make the game worst. Now most ftp games like Lost Ark are going to have a p2w aspect to it where you can get from start to finish in a couple minutes for the right price. These games usually allow you to reach end game fairly quick as they constantly focus on new end game content and to keep player bases they need constant catch up mechanics. When you add so many catch up mechanics it makes getting to end game faster. But this is a free to play pay to win model which is not a subscription based MMO in most cases.
This game does have FOMO, if you don't start trying to clear savage on release and try to do it a couple months later you will have problems. Every holiday event is FOMO as these items will likely never show up again and if they do it will likely be in the cash shop. Things like Eureka and Bozja are now barren and more difficult to complete. So to say there is no FOMO in FFXIV is untrue. But you have only played since December so you wouldn't really know this.
Now of course coming into a game that is in it's 6th expansion a couple months ago, you will have a lot of content to complete. That is common sense, but if you have played this game for a decade, this game has had a constant trend with it's content patches and the longevity issue with the content it releases. So when some one joins this game in the latest expansion and tells me there is a lot of content, it's hard to take that opinion with any merit as it is common sense. You see on youtube many people promoting the 6.1 patch as having a lot of content, but it in actuality is just a normal x.1 patch with about our 3rd or 4th pvp revamp. You can go and look at previous patches on the FFXIV website and see it's the same thing as usual.
