I agree, spears need a major buff. Mostly in formations, something weird happens there with friendly collission, Viking Conquest did this better than Bannerlord. For your suggestion, to balance the increase in spear damage, increase the heavy (mail+) armor values too without increasing any other weapon damage (perhaps apart from a slight increase in sword thrust pierce damage to balance the armor increase). A man in full maille should still be able to take a single spear thrust without falling dead even though a horse should be stopped just by running into it. Think couched lance damage, reversed effect, the horse's own speed working against it without the spearman having to release a magic button, the spear is still there even if you don't release left click at the right millisecond, no?
