rhodok spearmen weak? yah right. they are only weak when xbows arent doing there job right or you have them out of a formation. otherwise they pwn.
there is a reason they carry spears.1. spears stop cavalry. 2. spears are good in a formation in where they can suppor teachother ( as in not every spearmen has another person to fight thanks to the xbows and they can go 2 ro more vs 1) 3. spears have a good pearcing damage good against armored types a.k.a people most likely to survive the archer barrage ( and sharpshooters go through most shileds)
there infantry are nothing like any other faciton. they are not ment to charge in anything other then formation and because warband doesnt feature phalanxes they arent ment to charge. they arent good when a fight gets chaotic, they are infantry ment to delay and finish off a weakend enemy (cosnidering they have board shields and any smart player will put his x bows on a hill which means that the xbows can support hte infantry)
althought they would be better if there was a double line formation
There is a double line formation. Have them hold position and then tell them to stand closer. You can make the group less wide and longer that way. I think it would be a cool idea to implement a braced spear function, like in Native Expansion. It's like couching for spears (and only certain ones, like the awlpike). It worked really well in NE and turned mashed cavalry with it.
