The new spring bones are a nice touch, too bad we don't have some kind of environmental affect such as wind that could interact with said spring bones.  I also wish we had a particle system in CTA.  I know it's possible, even Moho has particles.  And finally, I wish we could export a scene from CTA5 to an external NLE or 3D app, with the scene intact, much as the After Effects export works.  While we can export out each layer, manually, we still have to reconstruct the entire scene, including transforms in said editor.  Makes using an external app to make our clips better a giant ole PITA! Unless, of course, one is willing to continuously pay Adobe for the privilege of using their apps (which I am not)
