The drawback of the AIC is that it also affects the hand that casts it, meaning that with the AIC active, Laura is rooted to the spot. She adapted by using Rin as a projectile.
Also, her dodging Blue Tears shots might be interpretted to mean that her shield cannot stop attacks with no mass, ie, beams.
Still, one does question the designers' idea for not including beam weaponry on a machine who's shield screws anything with mass.
Either way, I bet Laura's Second Shift turns her into Accelerator.
