I didn't know about being able to put it into three trees (assuming 31 points). I guess I misread. I thought you unlocked another tree once the first had 31 points, and couldn't unlock a third tree until that one also had 31 points (which is obviously impossible at level 85).

To be clear, some of us are unhappy that you have to put 31 points into a tree before moving to another tree. Some of us would like to not be forced to have 31 points in any particular tree, and instead go for mid-tier talents in both trees (such as a 20/21/0 build).
