I've selected what I think are the most efficient quests in Icecrown and have been doing them on two level 80 teams every day for a few weeks now.

Takes me about 80 minutes to finish 9 13g dailies and 2 22g dailies on 10 toons - right at 1500g per day. Both teams have epic flyers and now that I have two decent computers I run both teams at the same time. Cuts about 15 minutes off what my time when I was running them seperately.

They've all gotten the Bread Winner acheivement (make 10,000g from quests) and I only have 10K across all my toons. Makes me realize how much money I've blown since Wrath came out. :huh:

My wife would be proud.

Oh, and now I have another team at 77 with regular flyers - they'll be making the daily circuit too when I've got enough money to get them epic flyers. Then I can blow 2250g per day instead of 1500g! Woot!
