I've been searching for a good non-druid skinning spot for these for a long time, something that matches up to Falcosaur farming
I've done Eye of Azshara, Beach Crabs, Eels, Rays. But I think I found a good spot finally.
In Stormheim in the sea around the Goblin Zeppelin, there are Deep Water Clackers in groups of 11, and they are linked so if you aggro one, you aggro them all. Simply pulling 2 groups gets you 22 clackers that can be killed quickly, unlike the Azshara crabs. And unlike some other spots, they arent deep down in the ocean making it a "druid only" skinning spot.
I checked other areas with Deep Water Clackers and none of them act the same way, and the young ones in Broken Shore aren't even skinnable, making the whole idea of using a deep diving helmet and looking for these pointless, which you'd think was the idea originally.
