More about Atriox?

I am more than 100% sure I’m not the only one pissed off about the cliffhanger ending.
Don’t get me wrong, I loved the story, just that not much of it is really a story, more like simple 2 armies fighting.
Most of the questions are still left unanswered. Although they did announce a future campaign DLC, we don’t know if it’s going to be an expansion pack or DLCs telling more story arcs.
But I feel like the DLCs need to cover a lot more story than gameplay. Especially Artriox and the Banished itself.
In the trailers and interviews, the Banished were told to be this destructive, unstoppable force that no other enemy was like it. Yet in the story, they act basically like the Covenant, just with different units and color.
Same goes for Atriox, he’s suppose to be the smartest, unstoppable Brute. Yet he only appeared in 4 cutscenes, seen only to beat up Red Team (even thought it was badass), his origin story, talks to the Shipmaster, and be pissed off and looks at his army.
You saw no real tactics used in the game, no sense of danger or actual leadership. You can easily swap Atriox with some random Elite or Prophet and the Story would be basically the same (not so much in the fight scenes).
What we basically need is some actual details on Atriox or the Banished showing off their status of being this unstoppable army and not some Covenant 2.0
And please don’t kill Atriox in some cutscene in the start of the next game
