I think movement will not be the issue. the mastery at least helps a bit to still deal damage and we still have spirit walkers grace (with new glyph) and a short sprint.
what could be more disappointing is what happened to our aoe. it is no longer pure cl spam you have to use eq on cd cause of its damage. and with this you have to deal with eqs disadvantages too. (cd, mobs can walk out of effect)
