I actually thought this earlier, seeing all the loot in my pool, and fighting 6 mobs. Then remembered from their patch notes when they spoke about 'more then 8 chests....'. So they fully expected us to burn at a rate at which 9+ chests can spawn, which is only really possibly with a huge burning group. It's not worth giving up multiple dungeons for this content - and keep in mind, by the time Diadem 2 comes out, we'd have given up 3 dungeons 3.1, 3.2, 3.3. That's an entire patch worth of dungeons...
