When I made Vert way back when, his entire shtick was making barriers that he could move. Didn't even know Aura existed than either. Don't know if barriers are a universal thing for those who have aura, I always figured it was just a matter of specialization; some people focus more on being faster, others glyphs, some like to be on fire. It's not that they're all unique, it's just that some people are better at using a specific type. Like weapons.
