So far I've managed to learn about 150 different plans, blueprints and designs by farming the same locations multiple times a day with my eight characters. However, I'm now getting more and more duplicates, which is inevitable I guess.
So, other than Coldharbour and 'Hall of the Dead', does anybody else have any suggestions for a good/quick farming circuit, preferably outside of EP ?
Remember red = dead and a dead dd deals no dps.
