Yes, I recall that thread at twcenter.
Basically, the 'spear' attribute gives that certain weapon something akin to 'the touch of death' for cavalry and at the same time makes them horrible against infantry. Which is why if you notice carefully, almost any hit on a phalanxed unit still carrying the spear/pike will almost always result in a kill.
The mount bonus is usually better, however, the drawback is that it applies to BOTH weapons, which means units with primary and secondary (usually the sword) gets a bonus for both, making it unrealistic. It's quite useful for dedicated spearman though.
After some tweaking, I've felt that the mount bonuses for vanilla spearman are far too underpowered, especially if swordsman fare better. Take for example, Triarii compare to Principes.
Principes sword has the following values:
stat_sec 7, 2, no, 0, 0, melee, simple, piercing, sword, 25 ,1
Ie its attack value is 7 x (Rate of attack)1 = 7
Compared to Triarii:
mount_effect horse +4, chariot +4, camel +4
stat_pri 7, 7, no, 0, 0, melee, simple, piercing, spear, 25 ,0.73
So against cavalry its total attack is (7+4) x 0.73 = 8.03
Whoa, thats ONE whole point of bonus compared to a normal swordsman! *sarcasm*. Fat lot of difference that'll make in a fight.
So therefore if one wants to make spearman truly effective, you might have to change the bonuses manually to suit your taste.
Cheers!
