What if Bagains affected the spear line but Bulgarians lose halberdiers?

Imo this is interesting because it would diferenciate Bulgarian trash from spanish trash (right now are too similar in my oppinion since the only thing Bulgarians don`t have that spanish do ) and would make the spear line more interesting for them (they perform at the same level as Viking pikes vs cavalry as a comparison). I think this would also be a good reason to remove bracer for Bulgarians since this would make their trash quite unique while also nerfing the Krepost
