Been trying to play WoW again, since I was an alt-a-holic and my experience.
Leveling, questing - Leveling as getting experience is not that bad, quests are fun, but very easy in a way makes the experience rather boring (as no challenge is involved, not even as optional) (made-up challenges are not going to make it)
World content is ok by gw2 standards (like events and world quest), but nothing constructive or interesting.
Most of the game is oriented toward getting gear.
In PVP you can enjoy yourself usually, except when you are honor geared and everyone run around with conquest by now, demolishing everyone else, by simply having the gear. Now you could say you will get conquest faster in the next season, and that is just … meh
I haven’t played Mythic or Raid, because those require guild or pug life, and those can be quite toxic for no apparent reason other than the game makes everyone that way, as they require time to do and it is punishing players in a way if they can’t make enough progress in time.
Most of the game now is about the Great Push, and this is outcasting casual/fixed gameplay, now I don’t say this is wrong, but somehow this creates a very big discrepancy between new, returning, class switch players, and player pushing beyond a certain difficulty.
You might say that this will work out as people should play lower difficulty until they get better, this would be ok, but the party interface notion is no such thing, and relies on the community to come up with something. Good, they just ignore you if you need to learn, as don’t waste my time, and you just need some of these to feel discouraged.
Cosmetics are fun to get sure, but that’s all.
Pet Battle is a fun little minigame for a few, that’s cool too. (although I can’t stand playing it)
Old content is not favored in this game, so there is nothing really that can be done, as it is either easy, one-shot boring, or not fast enough for an adventure-style lore-telling book. (Grindy with no real reward whatsoever (gameplay experience)
Well, I think I just will log in once in a while, to see what they add in-game anything actually fun, or feels worthwhile, watch Bellular for lore, or perhaps get a game mode of its own with fixed progress like the old times.
Add non-timed Mythic, which has no high score, and gear that is not compatible with Mythic +, even raids. A chill Mythic, call it Mythic -, lol. It would remind me of the old Heroic, just fun and less stressful for people who just want to play and not make a sport out of it. This way you don’t have to remake the game mode, but still get one.
Ps. Have fun, if you can ! 
If you have any game mode, or fun to share please do so, if the game needs people and communities, they need a place to stay to play and nothing keeps them here if not something to do, they can enjoy!
