Hello.
It seems that the shield+short spear weapon combo is practically non-existent. I would guess that it is because this combo is completely ineffective against someone wearing armor.
Two questions:
1: Why is armor so complicated? Why not simply "ablate 1 hit"?
2: Why is stabbing so strange with how it interacts with armor?
Third unrelated question:
3: Why do 2-handed red swings damage shields? Why not simply encourage flanking/overrunning against shields?
