Overall I think they should start where the last Warzone version stopped and continue from there. This would give space for new fluff.
Somebody said if a something like an Everasseur would be used from Cybertronic the Brotherhood would call them heretics. I think this already happened anyway, so why should Cybertronic limit themselves too much? Imperial takes this as an excuse since the founding of Cybertronic.
By the way the Scorpion is a beast, too.
