Ima be honest, I'm not really all that attached to the scabbards... only one that would have me like "damn..." is kinemon & thats only cause he's been with us for so long, but even his death wouldn't impact me that much.
I dont think anyone is dying, I'd like it because it would add some tension to the arc that I think is lacking... but for me to really be on board there has to be consequences to characters we care about but I doubt the strawhats will be put in that kind of danger so it'll have to be either law or kid which is kinda meh to me.
We'll see what its like when this raid/war is over.
