Mostly due to downtime of the healer, and wipes due to the really high damage trash packs that are in there.
Some dungeons require less cc, but using them are usually much faster than not using cc, cause aoe is not good enough for mobs to die faster than single target nuking. In addition to single target nuking reduces healer downtime by eliminating priority targets quick.
