Hmm. This feels like someone who was really upset about sao and wanted to do it "right".
Skipping the explanations for high level techs being done at low levels, party members who have active roles and understand mechanics, bosses that are somewhat interesting but don't demand exactly one way to fight them.
Still missing a lot though. A shield katar that counts as a shield, and a shield bash that cuts. Does this come from a novel or something?
