Man, I'm still really irked by what Caitlin said to Barry and Cisco in 2x17 "Flash Back" about the RF and Zoom, and how they both only moved their body as fast as Barry could as of March 2016. This means that they could only pack as much force and exert as much energy as Barry. It would be a lot more appealing if the speedsters in this show moved at varying speeds and didn't all have equal amounts of speed-force energies in their bodies.
