This should not be, I will investigate this now.
--- EDIT ---
It's not using movement abilities for me when I have them toggled off...
The Mover Toggle has 3 states:
AC - Animation Cancel, this attempts to cancel out the movement aspects of the Vengeful Retreat and Fel Rush abilities though it does not always work and sometimes causes disconnections (but works well enough for those wanting such features)
On - Will automatically use movement abilities
Off - Will not sure movement abilities
