Yes and no… Yes if you're already fighting and the enemy is in your face, also the enemy you target seems to have the uncanny ability to sense that he is being targeted and make a b-line for the caster. However, in the moments before actual combat and/or when the creatures are charging/closing the distance you can fire off a couple/three in a matter of seconds.
