Warband melee is SO simple though lol, that's why it's popular I guess.
I'm excited for that directional shield blocking mentioned in a Bannerlord video/interview or whatever, I hope that does get added if it's not already. Even if that's just effective against ranged or stabbing weapons, that's pretty meta-shocking. More archers in battles? More interaction to counter them (other than just getting to them before the shield breaks)? Hell yeah, I'm all for it. Plus it's way easier to practice directional blocking if you have to use it with a shield, if it's required against swings.
That said, a lot of Warband players just hide behind shields, so maybe it'll be less appealing if there's some level of difficulty even with shields. But sword and board fights are boring as fuck in Warband, it just comes down to whose shield breaks first.
