hehe keep playing,1 hour is not much, it will be come addictive.
I have always been a Gnome Mage. Mages have a ton of usefulness, ability, utilities and for being cloth wearers they have pretty awesome survivability especially if you go Ice.
I have been playing on and off for 2 years, it hasnt impacted my life. I pull all nighter to play all the time, but thats because i have insomnia. Many say it's addicting, i don't really think it is. I haven't played in about 3 weeks and my account is still active and i have 80's
I would recommemd if you decide to play, not to play a warrior. That was my first toon, and realized after playing other classes that i really didn't like it.
