As an adult who has a full and busy life and limited time to play this game, I truly appreciate the OP's info. IMHO we need MORE posts like this to assist the enthusiastic, but casual player. Unlike the kids, I can afford to pay for subscriptions to multiple MMOs, and desire only to spend my money wisely. Helpful threads like this one only serve to enhance my enjoyment of what is thus far a fantastic game.
To the trolls: I hear WoW will release "Mists" this summer. Please take your whining, sniveling, selves back to that game, since you hijacked it anyhow. As a reminder...WoW experienced similar growing pains before becoming what it is today. An important character trait for you kids to learn is PATIENCE. Read about it! Now go do your homework or study for an exam or something...
To Bioware: Please continue to update and grow this game. Your original framework is magnificent and I look forward to playing this game for many years to come. Don't let this game become another WoW, except hopefully in numbers of subscriptions. Could we have age-restricted servers?
