I've played WoW since beta, still remains my most played game ever. I forget how many days of /played I have but it's an appallingly large number.
Some of my favorite gaming memories are from WoW, especially WotLK's storyline, although I have to give a biased nod to Legion as my favorite expansion, since that's when I worked at Blizzard and was there when it launched hah. Great expansion with a lot of awesome moments. Definitely didn't like Battle for Azeroth that much, dont' hate it, just didnt' like it that well. Shadowlands was merely ok. The Jailer was neat, but some of the design decisions really were bizarre (no mounts in The Maw (except ones you unlock) I'm looking at you).
Dragonflight is most certainly a step in the right direction. I mostly log in nowadays to go fish and work on faction rep, and to work on getting even more mounts.
