I've only recently started getting into doing TDS progression, as I was gone from the game when it was modern. It's been a lot of fun, and I'm really excited for what people are saying about Thuli Island and the Parrot aug quest, as those are the next things on my list to do!
That being said, Degmar is the most relaxing zone ever to farm my powersources in. One of the first zones I've memorized in a long time, easy to navigate, lots of nice easy nameds to kill, everything is blind as hell there. It's a very positive experience doing things there, I look forward so much to the following 3 areas!
