Well quite simply, where the hell is the thrust with the polearmrs, particularly the spears ? I can guess (and do hope) that they will rework/refine the polearms combat system, but at least give the chance to use one of the primary function of a polearms, poking at a safe distance the enemy ! And too, I must say a polearms are NOT slow and sluggish, it’s quite fast, because you’re using the end as a lever so you do big movement with little force.
Here a video that talk about this a bit: https://www.youtube.com/watch?v=7AikYrawU7M
This channel is awesome by the way, and he has many other video on polearms and others weapons.
