There is truth to this topic. I noticed that you can actually do manual animations by moving your character certain ways in combination with one of the class's existing skill animations and it looks pretty cool. In example, during one of the skills if you jump while executing it it creates a very neat looking animation. Another one is by spinning your character during mid animation and it looks like a blade twister holding dagger out while you spin. Don't remember which skill they were for these, but those are just 2 examples.
