Umm... O.O I think it looks kind of fun? Does anyone do it?
I mean it looks really stupid watching some Youtube's that have like two kids LARPing at a cosplay convention who suck at the weapons they do and clearly BS all their moves and have crappy costumes.
I think it would be awesome if it were like martial arts, where characters would spar or do like a two man staff or sword form.
No idea why people don't just use dou swords in their LARPing, they're practical and safe for fake fighting.
