I used to be addicted to WoW, Back in 2007 the days of Vanilla WoW. Me and my mates from school all played it, There were 6 of us, It was a perfect set up as we could always go do 5 mans. We also had our classes sorted, I was the only healer though, So when I was offline nothing happened.... We had our own TS surver too which was pretty gnarly
I tried playing it again last year, But with different friends, But Only lasted a few months. Never again will I be able to capture the fun I had on that game with those original 5 friends.
