I'm jumping in late on this but I feel like this whole realisation might be exactly what the whole movement needs. S5 for me started out as a great, fun read - Saionji and Anakin's Excellent Adventure, the wedding as a setpiece, hopefully leading to a final confrontation with Akio and leading into the redone Day of Infamy.Instead what seems to have happened is it's gotten sidetracked twice - once with the DSM Panic stuff overshadowing the Tau Ceti stuff, and then again with the Avatar stuff pretty much barging in and taking over the place. From a reader's perspective, especially coming off a recent re-read of some of the S1 stuff, it feels very different.
I think you essentially have two stories going on right now - the Korra stuff, which seems like it's what you want to be telling, and then S5 as it originally seemed to be progressing.
As I said, late to the party and all that. But there's $0.02.
