Can there be too much WoW?

After reading a fellow Death Knight's blog on the same topic, I thought I should share my take on all this as well.
This is a topic that most WoW players have heard at least once in their time on Azeroth. How much is too much? Ultimately, I believe it depends on the person. Some people are totally happy with only being able to play a few hours a week (thought I tend to believe some are throwing their money away if they're not logging in for days at a time but who am I to judge!), others want to devote every waking hour to the game. I've had friends that have done this. Hell, I've done this. I've already given my story on my character's up to current so here's the side on the other side of the PC:

I started WoW during the Public Beta. I had been waiting for a long time to try it out and when the Public Beta sign-up went up, I threw my name in ASAP. I got in and started playing my Dwarf Paladin 2-3 days a week. Not a lot but the servers were incredibly unstable and constantly going down so I played whenever I could. When the game went live, I bought my copy on the night of release. I continued playing 2-3 nights a week on top of whatever else I was playing at the time (no MMOs). My girlfriend at the time didn't seem to mind. I still hung out with friends, went to work, spent time with her, etc. Slowly I started ramping up my play time. We moved to a different apartment together (a 2 bedroom) where I was able to have a room to myself for my computer, TV, game consoles, collectables, etc.

Around this time, we began to have problems in our relationship. I withdrew into the game even more and as I had recently hit 60 (game is still Vanilla at this point), I wanted to experience all the end game had to offer. I was running 2-3 5 mans a night with a group of friends and totally ignoring our relationship until it went bust and we split. I moved into a place of my own and continued my long hours of WoW.
Soon afterwards, due to financial reasons, I had to move in with my mother. I was holding 2 jobs, working 12 hour days Saturday-Monday and then 3rd shift Tuesday & Wednesday. Whenever I was at home, I was usually playing Wow. I took some time on Wednesday afternoons to get up and go ride BMX with a couple friends (we all needed the exercise) until I flipped my bike and broke a toe but this was about the only outside interaction I had for most of that summer.

I entered into another relationship and tried to limit my playtime to spend with her, which I think I was mostly successful at. We moved in together about 6 months into our relationship and I got back into a pretty extensive play schedule. About 2 months into living together, and me raiding 3 nights a week, we learned she was pregnant. Then I lost my primary job. I went to working 5 nights a week, 3rd shift. We started having problems in our relationship (not related to Wow this time) and I eventually decided (April before Wrath dropped) to stop playing. I was sitting at my desk one morning and was frustrated that I was bored. I didn't want another alt (thought none of them were 70), didn't want to play the ones I had, didn't want to do any professions and I was starting to tire of raiding. So I quit on a spur of the moment decision. I cancelled and vowed that I was done, I wouldn't be back. I felt that I owed it to myself, my unborn child and my girlfriend to stop playing and devote more time to real life. I still gamed but nothing that required vast amounts of time.

I tried to stay away from Wow and Wow related news but being a gamer, I still read about it from time to time. I had no bad feelings towards the game but felt my time in Azeroth was over. September of that year, pre-Wrath release, I got a new job. Several people I worked with played, including one of my managers. I was still working 2 jobs at this time and was at work the night Wrath dropped. I managed to get a Collector's Edition (oh the perks of being an employee at a 24hr store when a game comes out). I went home in the morning, installed all of Wow plus Wrath and loaded back into Mannoroth, telling myself that I was not going to get sucked back into raiding again.

I ended up leaving Mannoroth for Zul'jin and joining my manager's guild. It was a very casual guild, mostly a friends and family type. I promised my girlfriend that my days of hardcore casual were over and for the most part, they are. I usually play 2-3 nights a week with Fridays guaranteed (I Main Tank the run, kinda need to be there). So far, it strikes a good balance of family and Azeroth life.

Are you someone who want to devote every waking moment or are you someone who enjoys a few casual hours a day/week?
