For me, BRD was a nightmare that never ended. Only did about 20% of the instance, even at level 56 I was having issues. DM East was pretty easy though.

I wasn't able to do scholo/strath without getting a decent amount of Outlands gear, but they are incredibly fun. I would do UBRS but am too lazy to do the key quest. However, the scholo key quest did offer good XP and was easy.
