Some things I think would be nice:
Returning Overhead Attack for Proper Weapons: Weapons like: Longaxes, Clubs, Hammers, Halberds. (Seen some short axes and hammers using the old one)
Pikes only able to Block Trust and Overhead: Otherwise there would be no pike fencing.
And it would make the Pike weaker while not making it totally useless against just about everyone like people here want.
Give the Pike the new Overhead Attack: Regarding above point. New animation fits for it.
