Spears feel wrong
Spears hitting multiple targets with one hit feels really wrong to me as a specialty of this type of weapon. Couldn't they have something more sensible, such as a greatly enhanced bonus when counterattacking or a defensive bonus when defending against counterattacks? Ideally, there would be something like mounted units, against which spears should have a bonus, or increased melee range, but I see that will not be happening. Impaling multiple enemies feels counterintuitive, cheesy, and immersion-breaking.
