When an outdated, 12-year-old game that charges 15 dollars a month in order to play (WoW) is still the most dominant of it's genre, you truly must understand that this genre is dead.
If by "outdated" you mean receiving semi-regularly updates to all aspects, then I guess the beginning of this statement is moderately correct.
Although by that same logic sports games (Madden, NBA, and FIFA games) alongside FPS games (Call of Duty) are dead genres as well. I mean, the same games which get updated and re-released each year are still the most popular (Somewhat speculative since Call of Duty doesn't give much detail anymore on concrete numbers).
I don't get it, why can't an AAA game company take up the task of making an amazing MMORPG instead of constant FPS after FPS.
Which AAA game company that makes "FPS after FPS" are you talking about? If you're thinking of either the Call of Duty or Battlefield series, you're a moron. Why would a company with a successful franchise in a specific genre ditch their franchise, and their genre, for a speculative play in an unstable market.
Instead of dull pointless quests, make levelling up my exploring the world and killing enemies and collecting loot like Path of Exile or Diablo.
Congratulations, there are a decent chunk of games which do this already. Someone else mentioned Black Desert, there's also Tree of Savior if you need another completely different title to pick from.
Instead of a Pay to Win market elements, make it only cosmetics/skins like League of Legends.
Once again, there's quite a few games that do F2P models very well.
Instead of dull boss fights, make them exciting and adrenaline rushing like Bloodborne/ Darksouls.
Like... raids? Pretty sure I'll take launch-version Experiment X-89 in Wildstar over any Bloodborne boss.
Instead of clones of the same class running around, make player make their own classes/build like Path of Exile which establishes uniqueness and variety.
How about we don't and realize that this would be a horrible design choice for a MMO. There's a reason PvP is mostly dead in Path of Exile and 4-5 threads dominate the top of each class-specific forum on their website. Certain builds will always be better and preferred in group content, and having such variety makes PvP balance a nightmare, if not straight-up impossible.
Instead of the old bird eye or third person view, try to establish a first person view, maybe the players will like that.
lol
Instead of the multiple anime looking mmorpgs, why not make something that looks like the Witcher 3 so everyone can enjoy.
Sounds like you looked at anime-specific games, thought "clearly this is all that exists", and then decided to write this post. There's a reason we've had like 10 posts on this subreddit this past month about "need to find an anime MMO" - hint: they're becoming much less frequent and already are much more rare than they were back in 2006.
Why not take all these aspects when(and more) when developing and put them into an new, unique MMORPG that players have been waiting for over 10 years.
Why don't you just go do all this then. I mean, you've clearly established that this is the correct formula, and there's 0 risk in these ideas, so it will be guaranteed to succeed.
Oh wait.
The genre isn't dying, people are just becoming more determined to ramble on whatever public forum they have access to about how much they think games are deteriorating because they have no ability to understand that they're seeing things through rose-colored glasses.
When you go from single player games with bland and basic storylines, uneventful combat, and nothing to do after you beat it in 10 hours to World of Warcraft, with years and years of lore as it's foundation - obviously you get culture shock and fall in love with it. Then after years pass you grow tired of it, and think "Wow, why can't any game make me fall in love for 6+ years anymore".
