Brayflox Longstops, from the healer perspective, is when I noticed that damage just ramped up. Gladiator or Marauder, it seems like, "whoa!"

And crowd control has made a HUGE difference in this dungeon.

Also, there seem to be a good deal of patrols as well, which may make a two to three mob fight become a four mob fight, in which case, if crowd control is broken, someone usually dies.
