LEAST FAVORITE- Maraudon- By far the longest 5-man I have EVER done. You can do ZF twice before you finish Mara.

FAVORITE- Ragefire Chasm. I know, everyone's going to laugh at me, but its easily accesible, easy to form a group, fast to urn and there are many quests. WAY BETTER than no special loot Stockades. Pfft. Stockades is annoying, definitely ranks 2nd least favorite.
