Just some ideas

I hate to break a dream, but you'll never be like Cloud (not related at all to FFXXIV's lore) nor kirito (nothing in common between FFxiv and Aincrad, except the "MMO" part).

Also, "dual wield" was a hacked ability given by Kayaba Akihiko to create the "hero who saved the players", I really doubt you'd ever see it in a SAO-like MMO

I don't know, I can see a cloud skin for a warrior axe from some sort of event being possible at some point.
