Which Manifestations to bring with Skragrott?

After the recent changes concerning GG and their Bad Moon mechanic, I am wondering what manifestation lore is best brought with my list featuring mainly squigs and troggoths, lead by the great skragrott. Is it best to run some general manifestations or use the GG faction manifestations because of the way malevolent moon works now?

"Friendly GLOOMSPITE GITZ units are under the light of the Bad Moon while they are wholly within 12" of this MANIFESTATION."

I wonder if this is now an auto-include also considering I plan on bringing skragrott as my general.
