Even better, if you have a class that has SoW or can get it from someone do it. Also, although I didn't do it myself since I just got back to the game, it seems to help on the agi quest if you have someone in group stand by the rock to act as a homing beacon. As for the sta one, unless you're just the right class and built exceptionally well, you can't solo it. Even though the mobs are rated lb at 60, they take damage as well as a mob on PoD. Definitely need at least 2 people to finish the last few off.
