Miriam's stance

What Chuckles said. Ideally, every weapon would have a different hitbox and attack speed, but if it goes the route of the DS titles, it would be meaninglessly bloated. If it worked akin to SotN or OoE where you could wield two weapons at once and the order in which you used your attacks made a difference in what your attacks would turn out to be, that would be the coolest thing in the world, especially if holding up or down varied your attacks as well. That would kind of be my ideal design document for a Castlevania title, honestly, as well as having Adventure Rebirth-style jumping and no leveling up. That's a discussion for somewhere else though.

If stances have to be shared between weapons, then the shared ones should make sense; you wouldn't weild a claymore like you would a rapier. I'd also like to see the katana be its own thing since it won the Sword or Whip poll. 

Than again if we assume we're getting six different weapons types (based off of Sword or Whip) then I don't think it would be very difficult to have each have their own unique attack aniamtions and stances to accompany them.
