I played because my friends played. There was something relaxing and mindless about the never-ending chain of fetch quests, but it was too repetitive to hold my interest forever. MMOs are not for me because I don't like having to grind or rely on others for progression so I never did instances.

That being said, to this day I remember my one and only PUG run of Zul'Farrak. Mid-2000s sometime I was playing a troll tank warrior and that group was solid and everyone did their job and I tanked the entire pyramid fight and nobody died and I felt on top of the world. Good memory.
