..my pattern is 1 of 3 directions (coming from north east, north, and north west)

First off, you do not know where I am going, except for a general area (1 of 3 areas actually) and than you do not know how far/close I will get, but you will have to decide, before I bust out my orb, or 1 part of your life is gone, and I'll do it again and again..

Secondly, the aiming involved makes being accurate take atleast twice as long as busting out an orb, simply because orbs radius is MUCH greater.
