I think a double episode would've been better, where the first episode involves RWBY, JNPR, and SSSN fighting the grimm, but they don't manage to get an upper hand, and the second episode involves CFVY, the teachers, the Atlesian military, etc finishing off the grimm, along with the other stuff.

In order for the grimm to really and truly appear as a threat, a grimm invasion needs to be something that first-years cannot handle themselves.
