Don't start again!
I totally agree with Words of Wisdom.
I did the same thing. I had a level 60 that was collecting dust, and decided to check out wotlk. I got to eighty, started feeling that urge to be there for my guild mates, and there I was...obligated to play, hooked on gear upgrades, and wondering how I would have enough time to get into a nice raiding schedule.
I realized I would have to sacrifice too much to be successful and competitive. I like that pause button most games I play include. :P Plus I just felt like a mindless zombie, a cash cow for Blizzard to milk.
So I QUIT BABY! God it's a great feeling. 
Person 1: Does Valkyria Chronicles have trophies?
Person 2: No.
Person 1: Forget it. I'm not buying it.
Person 2: Wait! It's amazing! Unique, charming, drop dead gorgeous... Hello?
