Big problem is that spears are handled as strictly a slow, clumsy reach weapon.
There is a reason that in Asia, the Middle East, and Europe, for about 4000 years, with a little blip for about 400 years, spears were the dominant melee weapon of choice, and swords were a secondary sidearm.
Spear thrusting, needs to be much faster, and actually do real damage. That's the fix. Spear thrusts are quick, sudden jabs, not this long wind up and slow delivery. Fix that, and spears will be far more useful.
