without spoilering me, is there really anywhere near the amount of content in DF than we had in the previous expansions?

Yeah, I could just ask google but I really don't want any spoilers as to what systems, activities or minigames await me later in the game.

As reference: I'm a solo player who enjoys playing open world content. In Shadowlands we had 4 covernants where each had it's own fun activities and minigames. The garden, the Kyrian arena, ... In BfA we had entirely different Horde and Alliance leveling experiences.

Now as I just started DF and finished two of the four zones, I wonder how the game will surprise me when I'm done leveling. All I see at the moment are four reputation tracks with some interesting items to unlock...

Could you tell me without any spoilers that I am not seeing the whole picture and there will be fun content besides a reputation track? I just can't see it at the moment and I wonder why people are so happy about the expansion compared to SL. I certainly do enjoy it, but it feels like more classical WoW than modern WoW which has a lot of side content / activities besides quests and dungeons.

Personally I enjoyed SL because I'm not one of the majority who falls into the power grind. I simply stop when there's nothing fun to do and return at later patches. Group play isn't my thing in this game, too toxic.
