Just passing this spot again with my 48 Shade and decided to see if they have fixed the en-masse agro you sometimes got from these...
After I killed 10 of them, I'm guessing they did, but I also noticed that I made nearly 10g from these 10 and also got 3xp items to hand into Maible up the tower in Tir Urphost, so some nice and easy (health never went lower than 80%) solo kills and cash if you are in this area imo...
