TIL Spearmen with shield attacks 30% faster than the shieldless version

So even though the damage number stays the same, the shielded version likely deals much more damage per second.
~~This seems to be due to the animation changing from two-handed spear to one-handed spear.~~(edit: Apparently, animation doesn't have much to do with it)
There were some interesting findings like this while digging through attack speeds.
For example, Sauruses and Black Orcs have much higher attack speed(3.7) than most other infantry(4.3), Temple Guards attack much faster(4.0) than fellow halberds(4.4\~4.9) while Halberdiers have very low speed(5.6), and so on.
