I have more
I have a lot of debunking to do!
Asuna’s Rapier - Her rapier was left behind when she died because she and Kirito shared an inventory, due to their marriage. All of her items became Kirito’s when she died. It remained out of storage because a vacancy had just opened in Kirito’s weapon equip slots due to Dark Repulsor shattering.
ALO Dual-Wielding - Actually, no sword skills exist in ALO pre-Aincrad. Swordplay in ALO is achieved basically the same way as it is IRL - swing the pointy thingy and hit the enemy. Swinging two pointy thingies isn’t a problem because, as sword skills don’t exist in the first place, a sword skill is not mucked up when two swords are used as it would have been in Aincrad. This is different after New Aincrad - as explained by Kirito in the anime.
