I don’t think it needs to be.This is why in CMA, the staff training is always before the spear training.
The spear is a foot soldier’s weapon. It was easy and quick to train (relatively speaking). It was cheap to make, and easy to arm a lot of guys with it. Conscripts were brought in and given a spear, then drilled in its use. I do not believe they were taught staff first, if they were meant to fill the ranks of spearmen.
