Well, it certainly wasn't quick. It was much like trying to solo an AV, each spawn took around 10 minutes or more to bring down. I was surprised at the number of Elite Bosses in the spawns. I would have expected only 1, but at least half the spawn is an EB, which I guess helps with the level shifts, but it's a lot of damage.
Also, I'm wondering can the new inspirations drop from the regular spawns? In the spawns I was able to clear I only got a few regular inspiration drops so I wasn't sure if the new ones should have dropped there or not.
