Here is the problem. You played WoW for too long. You instinctively reject anything that doesn't work exactly like WoW.
This is a problem many of us have adapting to FF. It takes time. You are too used to the way WoW plays. This is not WoW. You do not rush to end game. The journey matters here and is the meat of the experience. The end-game is not a daily grind that will give you a chore everyday. It is something you can end in 6 weeks (depending on your group and not including ultimates). End-game in FF is everything. It is not one single thing. It is professions, it's PvP, it's fishing, it's triple triad, it's chocobo racing, it's eureka, it's bozja, it's leveling your trust, It's roulettes, It's ishgard restoration, it's housing, etc.
This is not WoW. The game is not designed to chore you up to having to log in everyday in an endless power grind and do some horribly boring and unrewarding piece of content. FF tells you to go an do whatever you find fun... or don't. Taking a break and just coming back for the next story patch is also fine. The game is not an addiction. It's a passion.
If you don't get used to what this game is doing, you will not enjoy it and that is completely on you.
Sure, maybe you honestly don't like it. But, unless the art style just simply isn't your thing or you truly don't care about story (and therefore this is not the game for you), i don't know how anyone can think the game isn't good.
I will use a few examples like: "oh no, it doesn't auto dismount me when i want to attack a mob". Who said this was a requirement? The game doesn't have mounted combat (who knows in the future) so it makes perfect sense to get out of your mount before you can attack. You just got used to it being that way. Nowhere was it decided it must work that way.
Also: "oh no the questing is not nearly as good as WoW. It's all looting 3 things or killing 3 mobs". Sure, but WoW's questing is based on gameplay, not story. You get some cinematic after you clear a zone. That is dozens and dozens of quests. Many way more boring that rather than 3 objectives require you to do 10, 15, etc. It's padding out the length of the experience.
FF doesn't work like that. FF questing is just a bit of a break and context to the story being told. They are the break between your story. They are there to make you travel the world. They do not need to be super creative, they need to be non-intrusive.
Sure, more variety wouldn't hurt, but these quests aren't the meat of the experience, the story is.
Different games that do different things.
