Ran the Droaam twice yesterday. Both times on my level 20 rogue. Solo on normal the first time, and then elite with a favored soul and wizard (level 18 for both of them, I believe).
First off, I heard no DM voice for any of the 3 quests.
Diplomatic Impunity - Best part of this quest was the cliff shot overlooking the Droaam invasion force. Only issue I had was I disabled the traps for the final fight area, but they still activated.
Frame work - Love the layout of the quest. The ballistae were a lot of fun to use, but they seem to launch me too far. First two times I used the ones on the outside, it overshot me completely and I landed outside the minotaur area. I like the very last objective for the kill minotaurs objective (kill something else) and it is nice to see that if you complete it all the way you are rewarded with loot. Haven't managed to complete it stealth yet.
Eyes of Stone - I liked how the boss fight was set up with the ability to stone her if you can get her into the mirror.
Overall, no real issues that I saw (besides the trap and DM voice issue I already noted) and a great group of quests. Did a wonderful job
