Hmm, not a bad idea - but won't work too well for me. I'm usually not the type who has time for instances, as I often have to get up and do something else unexpectedly. Usually I do instances once I've out leveled them and can solo them on my own time. I think I've got what I'll try - I looked over the Priest tree, and I've noticed that I almost never hear anyone talking about Discipline Priests. I think I may take that route. So it's a bit of a challenge, as well as a theme. I'll put about 10 points into the other two trees (Spirit Tap, and Holy Specialization), and then I'll put the rest in discipline (or I may not do the Holy Spec one).
