Hmm... Ok, let me give it another go..
To effectively be used, the user needs to focus on his target and concentrate on the killing intent towards it, meaning that one must see the target and be focused on it. - That makes one easily susceptible to genjutsu and another type of counter to divert my attention, this toppled with the fact that it's distance effects its level of potency means that I have to get close enough to actually make it effect the opponent. (Close range) But that would be a waste of a technique and very dangerous for the user in most situations (You throw away your advantage.) Long and mid range barely makes it effective enough to completely immobilize your opponent. Meaning that the jutsu itself can considered useless against any strong opponent. Short range or long range you are still putting yourself at a disadvantage.
