Don't know about the Nids campaign, but the Necrons one introduced a civil war between loyalists of Szarekh and the Sautekh Dynasty of Imotekh the Stormlord.
Sorry Gaz, this will be the last thing about the coherency topic from me here.
I never said that I want for AoS to become r&f game. My response was only to show that you don't have to memorise that table to play KoW.
What is there to memorise? This chart is only important when assembling and putting your minis on trays or multibasing. During the game you can tell what the unit is by looking at it. Their footprints are different enough to make it impossible to mistake them for one another.
Literally, the old adventure said that you can save only the people not the place. So this is not a "GW destroys another CoS", it's a continuation of the previously established situation.
No, Destruction is not about "bringing the civilisation and whole reality to a primordial sludge". Destruction is about "destroy the castle, let them rebuild, repeat".
