So I am wondering about the game mechanics in regards to troops at the castle and Primarchs on that castle.
I have a number of troops stationed at the castle say 10k. I have some in a nearby safe zone and only 1 on my Primarch. Should I keep 2 to 3k on my Primarch or just leave them all in the castle?
How does the mechanics work when attacker’s hit the Primarch at that castle?
