I've had this thought in my head since the DLC came out. how odd/fun would it be if Alucard had some of Sam's moves from Metal Gear Rising. Like a special counter wher if an enemy strikes while Alucard is blocking, he would deflect the attack and retaliate with a flurry of strike while wielding the Crissaegrim in one hand (like hos if you strike Sam in his bossfight when his sword glows orange when blocking). i think it would be a bit humorous.
i also noticed the reference to the Valmanway (SoTN version of Crissaegrim) which is a wind based sword. Alucard has several moves in the DLC where he generates a gust, vortex, tunnel, and more of wind to use against his foes (sort of like the Void Swords certain attacks). An example of this would be wher Alucard is in the air and he spins like a a propeller with his sword, which creates a cyclone underneath him that pulls the enemies on the ground closest into the air wher he can strike them.
