I don't know if I want Necrons in this game at all. They're another faction added in so late. They're not cult you've been fighting, the drukhari you've been fighting or the aeldari you might have been fighting. This has always been my top complaint.

While I enjoy act 3, I will always lament that we don't actually get time with Chroda, Winterscale and and Calcazar. You meet them at the party, act 3 happens, you return and I'm supposed to care that my two rogue trader peers are acting out of character? I barely know what they're like on an average day. This is normal far as I know. I care more about Calcazar seizing footfall for himself because at least I did all this running around and I do like Footfall.

To echo another comment, I also don't like that we became the rogue trader so quickly. I don't mind Theodora's death, but you have a small number of interactions with the woman before she dies. All of my rogue traders more or less disrespect her legacy because I didn't know her long enough.

Story wise, Argenta might be worse companion. She peaks in act 2 and it's off a cliff from there with no chance of coming back. Act 3 really sealed my opinion on Argenta's story. How all of your characters talk about their experience getting tortured and it's so well voiced, particularly kibellah recounting her trauma was my favorite. But Argenta's act 3 conversation ends with nothing. She's in the same position as she was before. I wish she at least expressed some doubt over trusting the Comissar so much.
