User blog comment:Waters Knight/Monty Tweets About 'Dust Levels'?/@comment-9090085-20140624005601

Seems pretty straightforward to me: he just makes note of who is better at what thing and how that effects who wins a fight. (If you've ever played Fire Emblem and had a General and a Rouge face off, you've seen the hilarity of 0% accuracy attacks going head-to-head with 0-damage attacks)

Of course, seeing as he has mentioned video games as inspiration for how he animates, he could be mentioning how there are "advanced techniques" that you learn as you hone your skills,(like how anyone can throw a punch, but you need great skill to throw a punch that cracks bones) that just so happen to fit conveniently into a "skill level" type set-up.

In fact... I think we have see a little of that in the show already: We've seen just about everyone use Aura to prevent themselves from getting killed, and they still get tossed around like they took the blow full force; but we've also seen Ren and Cinder block blows with the palms of their hands, and they stayed rooted in place(Ren is most blatant).

What does this mean? I figure it means that while everyone knows the "full body shield" use of Aura to reflexively protect them from blows they weren't expecting, Ren and Cinder have learned a more advanced "localized shield" technique that, while protecting a small part of the body, is much stronger and may "use up" less Aura then the full body shield. (if you've played "Starfleet Battles" you might know what I'm getting at with the "reinforce all shields" and "reinforce individual shield" distinction)

Well, that's what I think.
