Probably I should have emphasized the word "N O T E S" more Of course, you have to know the quests for doing this. I just wrote this because for my first crew I tried a solo player guide from www.wow-pro.com but it wasnt good for a 5-man party. Durotar is a great starting point to get to all big cities and starting areas very fast while doing killing quests. And maybe some players don't think of doing quests 5 levels lower than your group level when you have a full group.
But thanks for your good input
