I'm assuming at level 38 you don't have the intimidation trait and you definitely don't have Storm's path yet. You should pop Warmonger to get initial hate THEN hit Defender to boost your enmity then use Brutal Swing/Brandish/Disorientate and finish with a Storms Path you will have their attention, believe me. Just pray there is a CON near that is good at their role.
Why would you need to do crowd control in Behest anyway? Most mobs are in pairs and if there are other mobs attacking then you ignore them until their names turn red. Doing anything else is just pissing away perfectly good SP.
