No, we tested it also by holding down the attack button with 3 different armors, all tests were at the same place.
Seiryuu Uniform -> slowest attack speed
Byakko Uniform -> a bit faster
Wolf Belt -> at least two times faster than the others
This huge difference leads to unequip the new armors, staying at Wolf Belt and knocking enemies like before
And no, except of changing the armors we didn't do anything else.
