Just a tip/guide for those who are trying to level skinning, leatherworking, trying to buy patterns, or trying to just make gold.
In the outer ring of Deepholm, between the 9 o'clock and 12 o'clock areas, there are large giants killing groups of mobs running around. Specific areas are anywhere between 34,53 and 32,42. Above these areas are large groups of bats, usually 10 or more. These bats have 5,368 hitpoints each. There are anywhere between 3 and 5 groups of bats flying around at one time. Range pull these, aoe them down, and skin. They always give a Savage Leather (whole ones, no scraps), and sometimes a Bloated Stomach with random Volatiles in them. The bats always stay up, when you kill one or two, more spawn, just loot, fly around, and find the next.
Total time is minimal and the reward for the effort is good. Just passing good info on.
