+
+The resulting rig should be easy to animate, by selecting the nodes and rotating them you can animate forward kinematic (FK) efficiently. 
+
+For simple objects and rigs this is fine, however the following problems are common:
+
+* Selecting sprites can become difficult for complex rigs, and the scene tree ends being used due to the difficulty of clicking over the proper sprite.
+* Inverse Kinematics is often desire for extremities.
