I think the biggest challenge with the movement is the ability's animations. For instance, Cauterize/Rupture and Force Leap/Charge seem too lengthy and require you to commit to a specific position for a moment or two while the boss is running away.
This is particularly a problem for Zealous Leap and Force Sweep, which have built-in self roots (Zealous Leap also has a slightly random component to its animation, so you can end up leaping into stupid). As for Cauterize, if you're moving when you start the animation, it acts as if you were jumping (i.e. with spacebar), and so you can actually control your movement while in the air during the animation. Still requires some commitment before hand though, which is annoying.
