I have to really wonder on why those early ones prior to Haukke Manor are/were agonizing? But then again, I can probably guess the answer. Probably pulling more than the groups gear and experience can handle, especially if people are not interrupting or avoiding certain enemy actions. Its been a long time since I have done Satasha, Copperbell, Tam-Tara, Hatali, and Totorak, but Hauke Manor/Brayflox was where the kid's gloves came off. So they would have really have had to mess up the early skills to make the training dungeons painful. Though I think the issue is more of expecting geared farming strategies to work during the ungeared leveling process.
