Yes, could the features be reintroduced by anyone? I play as an English bannerman and I'm finding that my Welsh bowmen have to be placed unrealistically far from (scale estimate) my infantry. It's gone to the point that my archers are always vulnerable to cavalry attack, esp by light horse.
Also, I know that there was mention of it being "warband" mechanics (in another topic), but I believe there are "Only use ranged weapons" options available in other mods, ACOK for example (if I'm not incorrect)
