In all honesty with all of the balance preaching that went on with Tanaka I would doubt that these level of weapons were ever his idea, I think the tier progression was Matsui's idea, and the only way he figured he could make it stand out is with these insane leaps, and he would be right, except we as a player base simply skip things like that every time because SE makes it too many hoops and to much time to bother going through the other content first.
