Playing this build will make you care about your positioning, awareness, perypheral vision and target priority. You will have to practice how to use every one of your defensive spells to its maximum potential, and make you think about defensive ways of utilizing your offensive spells, as you will literally be a oneshot for many heavily geared people. But with enough time, experience, a group of friends, and this toolkit at your disposal, you become a lethal weapon (and the number one focused person once they realize who is deleting them xD), and a great addition to every BG.
