When we were looking at this tree, one of the goals was to create a tree that bolstered a number of different (and less effective) builds. The fact that this tree can be used to good effect by Artificers, Assassins, Wizards, and maybe even Int based Rangers speaks to the advantage of a tree that is not locked to one class. We can focus on many play styles at once. That is not something we can do with purely class trees, especially since some of the classes that could use a boost already have three trees.

I honestly don't see where I have any points to spare for this tree on my assassin build, but I will play around with it to be sure.
