I recently did Downfall on my Warlock and I found the experience to be underwhelming, 1 wipe due to the Iron Star. Though perhaps I just got lucky and got a good group.

The hard part was waiting 30 minutes for our raid to fill after 2/3rds of the group left after Paragons. Are players really that afraid of fighting Garrosh in LFR?
Wings like SoO 2 and ToT 2 are the ones that I sometimes have a hard time staying awake on, the excessive amounts of trash packs are mind numbing. >.<
