The feedback will not be useless if you know how to use it. I was trying to help, I don't know why you got nervous man.
but to answer your question, they can be useful with small changes, for example:
-Orochimaru has the Kusanagi. This skills spend 1 Tai and 1 Random to deal 25 Piecing damage. 25 Its very expensive to only 25 damage, and because of this, nobody use him in ladder. When has the Constrict and bite available, he will spend 1 Tai and 3 Random to try to do 50 Damage. I said "try" because if the enemy stun him, He will spend 2 random to do nothing.
