There are clearly 2 different animations for the thrust attack on the spear and i am asking me if this was done on purpose to nerf the spear ! In the second video the spear is slipping back in the forehand while the forehand is not moving. In the first Video the forhand is moving with the spear.
This forces the player to watch their own animation and adjust their aim accordingly, rather than watching their opponent to properly block. That's a little overwhelming or overcomplicated if that have be done on purpose.
