I've found a couple of areas that have fast respawn times, but lots of mobs in one place that don't have stupid abilities like the alchemists or the life drain mobs near the graveyards.
However, wondering if anyone has found any areas that have 10+ mobs that you could gather up and have 2 or 3 areas that you could repeatedly farm for transmog items etc.
The one place I found is on the Violet Rise, which is a small island on the eastern coast. There are a bunch of raptors, handlers, shield guys. As a warlock you can farm quite a few with your voidwalker and seed, but there's really only 1 1/2 groups. They do respawn fairly fast, but the second group needs to be larger. Trying to scout around and see if I can find a pack that suits my needs.
