The game is indie-level the animations are sometimes janky, but that's besides the point.
The point is, the game above, depicts the long-reach thrusting weapons as a physical object within the game which, when "driven" forward will act as a physical obstruction to hinder the opponent and stop them at their tracks. It even depicts "driving the shaft forward" where the pole weapon is pointed toward the enemy and the player "drives it forward."
Now of course, in real life, people don't really move around at running speeds while using weapons, so in the game the wielder puts the shaft in front and runs around like a bulldozer. That would almost never happen in real life -- but again, the point here is, the shaft is pointed at the enemy, it moves forward, and it is treated as a physical object.
Bannerlord is not physics based, but there are still many options and different ways to depict thrusting weapons better.
It's just a big shame the devs pretty much have no desire to.
