Heh, my experience was the opposite. I played it for a bit (having played WoW during burning crusade through cataclysm) and had a lot of fun, but I stopped because it didn't hook me enough into playing long sessions or logging in every day.

If there's one game that does "not very fun (occasionally) but incredibly addicting" for me it's Old School Runescape. I started playing Runescape in 2006 and I still play in 2019 (with some breaks in between). I'm 21. That's most of my life.
