I've been farming them by catching up on my slayer deeds in the T6 areas... Wolves/Wargs in Enedwaith, Eregion, Mirkwood, and Moria, Beasts in Lorien and Mirkwood, Deep-claws in Moria, etc. The TP is nice even if I don't need the virtues, and you end up with stacks of hides. Off the top of my head, areas for these include: Wolf cave in northeastern Enedwaith, and wolf areas in Mirkwood (there are a few, IIRC). Deep-claws are near Dolven View in Moria. Beasts are in eastern Lorien near the Anduin and there are bears in the south. Happy hunting
