i got one of these in JP after only killing maybe 10 of these things. JP is flat out the best soloing ground for rangers 49+. Nothing aggroes you while you root/snare/DoT/plink with arrows....repeat. Decent drops in here as well. This eye of the griffon is going up for sale on bristlebane server today in the bazaar.
