The new profession system is awful. We wanted less borrowed power systems, they claimed they heard our feedback, then turned around and gave them to us in the form of professions instead of PvE.
Keep the work orders, remove the skill trees. At the very least, remove knowledge points and give people a set/static # of points from the get-go (that do not need to be grinded like Artifact Power, Anima, etc!) and allow respecs.
