Suggestion: I love the new skill/ability menu design since it's sharp and clean, but having that old grid view was very fast and efficient for finding and adding abilities to the skill bars. At level 70 there are so many abilities that scrolling through a long list to find 1 ability takes a while. I would suggest adding a "grid" view that you can toggle for fast ability drag and dropping.
Buggy: Serbule FPS is going crazy low if I stay there too long ... and I'm crashing if I stay there for too long. Everywhere else seems fine though. (note: terrible laptop, but never have it this bad)
Cosmetic: The Work Order menu description says "Rewards:" twice but doesn't list anything after the second one.
Update: the quest tracker window is actually pretty cool .... it was turned on by default with no way to get rid of it earlier so I was confused and had no clue what it was. Cool feature.
