I knew what I was getting into with GW2 and that's why I got it in the first place. I also liked GW1 but not as much.
I prefer rich experiences that add to the sense of immersion and world-building versus an extensive overlay of game features. That's why I liked Vanilla WoW over BC or WotLK ultimately, despite the latter two being arguably superior; all the while preferring Legion to just about every expansion post Vanilla.
When it comes to one-off experiences for a quick fix I tend to lean more towards shooters like Overwatch. I'd rather MMOs lean towards their RPG roots and be something I get on when I want to delve deep into something for several hours at a time.
