...You do know what 'implausible' means, right?

I DO know that Myrtenaster uses Dust to create those effects. On the other hand, do you see anyone else performing the same feats with Dust as Weiss?

If you'd rather me phrase my opinion as 'It's not likely knuckle-headed, gun/weapon-nut Ruby is going to be learning to work what is functionally magic, when she's got such a fettish for shooty-shooty, bang-bang, kablooie fun' then I can do that.

Also, not everything in the trailers is actually canon. There's a thread on here somewhere where Monty mentioned that via twitter.
