Hmm well I played it for years. During that time I might have taken say 3 or 4 month or two breaks from it, mostly from boredom. Then they'd release updates or expansions with shiny stuff and I'd go back to hardcore WoWing for a while. Anyway, I last quit... hmm probably over a year ago now. It was not long after Ulduar came out. Anyway the final reason was that for one, all the people I played with for the most part either quit or changed servers. Two, I had most of the gear I could really care for because the game became so easy (we're talking pugging every 10 and 25 raid every week on a warrior and DK - granted we rarely finished whole things but since I put them together I made sure it was different areas). Three, I was bored of grinding heroics and raiding (or couldn't raid till the next week) so I got into Blacksmithing really hardcore. Every day I was checking the auction house for material prices and I easily was spending 1k gold a day on mats and crafting a ton of stuff (for a couple weeks I had no less than 150 items on the AH every day). My average income according to the stats was 3300g/day purely from selling blacksmithed items. Thank you gold farmers for farming all that cheap as hell ore! Anyway, because of that I bought all the best epics that I couldn't get on my own in a raid, I had a mechano hog for both my characters, and even a traveller's mammoth on my warrior. I had nothing left to do in WoW except farm badges for that new hippogryph mount from the tournament thing. Basically I just decided "I beat WoW" because I accomplished all I could have really hoped/cared to do. So I quit and that was the end of it I haven't played since. I gotta say tho Cataclysm looks good but I'll hold off. I might try a different MMO sometime but maybe not... who knows.
