how do you intend to have normal katana, dagger and kodachi users fight into a large sword user when their slashes cant be recoiled and can block? one of the main strategies to locking a player using such swords in place is to recoil them then slash rush around them. If, ontop of the higher range, the capability to backpeddle with it and a ping >0 you add non-recoiling and being able to block slash rushes, large sword users would basically be unkillable if played right. not to mention, incredibly unfun to match with even if killable.
