Yeah, you should do that. Her semblance is named Shadows in the DVD commentary and is clearly that Blake moves fast but not fast enough to completely disappear from enemy's sight, that's why she uses her semblance in order to distract and confuse her enemies. It's not like if the after images are because of her speed, if that were to be the case then Roman can do that to since he is faster than Blake.

Weiss' ability to move fast must be part of Myrtenaster's power. All her abilities come from her weapon, if she were to be disarm, she would lose all of her skills and Weiss' doesn't look like the type to fight hand-to-hand combat.

Ruby's semblance allows her to move so fast that she can completely disappear from enemy's sight, leaving a trace of red roses.
