I absolutely agree with you.
With my words I didn't mean that the First Order is abandoned. It's only that it cached my eye the fact that the existence, nowadays, of Servants of the Strife (Separatist Alliance), Guardians of the Republic (Galactic Republic) and Heralds of Hope (Resistance), together with the next releases of Phoenix Cell (Rebel Alliance), Skystrike Academy (Galactic Empire) and Fugitives and Collaborators (Scum & Villainy) leave First Order as the only one faction without a dedicated pack for itself.
Nevertheless, as you've said, it may come soon or, at least, at any moment. Anyway, First Order is a faction funny to play with, so I'll keep enjoying with it.
