I will say that infantry with a polearm can bring my horse to a stop but I don't worry I see cav running at me like I used to in Warband. I don't think I've been "one shotted" in Bannerlord at all. Cav now just bunch up and try to scratch each other to death with long sticks.Tried the « brace » option on spears recently, if you are not interrupted, that’s radical, the guy impales himself on your pike. And there are very long spears that could be used in a shield wall, the bearer being behind the infantry with shields, deadly efficient against cavalry charges imo.
Would be cool if the vlandian pikemen were knowing how to use it - and btw, make them useful !
