Asura Greatsword Placement
I don’t think its a concious decision to move the placement. I think its more just a consequence of the Winter greatsword having a smaller hilt than most. If they moved the other GS in your picture (or indeed many others) up further than the hilt would sit far above the characters’ head, which I assume they don’t want.
Greatsword placing and scaling for Asura is something which annoys me on a regular basis, but if they were moved further up to a more natural position then those with long ears would probably have clipping issues with the hilt.
Honestly I don’t mind how they’re placed, what is annoying though is how some of them half in size when you sheath them. I know they can’t really work around shrinking them down, but for some swords the jump in scale is huge.
