Rogue legendary daggers. These videos are the best thing they have done for the lore in a long time. Heres hoping they do many more of these.

What I found interesting was the time. Dragon soul's bosses died within several weeks of eachother, making the Seige on Wyrmrest take roughly a month. The Deathwing battle taking several hours doesn't suprise me though. Cool cinematic view of the fights.
