And for the record, I say this as someone who does follow the AH enough to turn over 5 to 20k a day when I feel like playing with it. So shove your 'herpaderp just buy it'. No. If I wanted to spend money to make money I'd just farm the herbs and sell high, then do my cards when they're low. All this does is turn another pointless chore into a tedious pointless chore.
Ill be honest i don't think I will ever understand that train of thought. You know how to turn 5k into 20k but you would rather go gather herbs for 3 hours instead of buy what you need.
Time is the real currency in wow not gold.
