One jutsu I hate with a searing passion that should be banned because of it's sheer stupidity, is Kawarimi no Jutsu. I find that anybody using this jutsu thinks of it as some sort of Hiraishin. Sense its not, its simply high speed movement like Shunshin, but with the completely asinine point of running BACK to only put a log or what have you in your place. Whats even worse is that the jutsu is described as, "....users replace their own body with some other object, generally with a block of wood, the moment an attack lands. This creates an optical illusion, making the enemy think the attack was successful." Really? So you just happen to have the speed to move faster than light, or fast enough to leave an afterimage, only to run back with an object from hammerspace for a ,"Ha ha, I fooled you!"??
Granted I could forgive almost all of this, if it weren't for the fact its a general ninjutsu. No genjutsu, no henge to make it look like you; you just do it...
