I was doing quests in the area today and tested the Onslaught camp out. You still can tag and get exp like normal, the drops seem to be the same as well. So the exp part is still good. I only cleared it two times and looted to see if loot got nerfed. It does seem they drop less cloth. But i did this for the fast exp and that still works. I did get some cloth and a few greens in two full clears though. It still a great place to boost from 68-73/74
