I do hope feints in Bannerlord (if they were to exist) wouldn't be exactly like they exist in Warband. Warband feints look utterly ridiculous and make no sense at all. The problem isn't the concept of having feints in the game, it was how they were implemented/operated.
There is little to no fluidity in how the weapons move while feinting, they mostly just appear where your next attack direction is. It is as if the weapon has absolutely no weight to it at all, so the character can instantaneously move its' arm to the new position. If there were actual animations for transitions between strikes it would look clean and feel more real while still having a decent skill cap. This would likely slow down the speed of feints a bit, but if the time to attack/block is properly paired I think it would work well. The chaining attacks look like an effort in this direction, though they aren't quite the same.
