I hope I am in the good spot to make such a post.
First I'd like to salute the entire team for releasing such a good game.
I already played dozens of hours.
Here's a list of what might need to be changed and a list of what may be added (I pray for that!)
What needs to be changed :
-Kastelan robots are way too powerful. They deal great damage and have a great armor. The armor should be lowered a bit, since it's a single unit and not a squad, firepower can't be reduced by killing a member.
-I don't get why when I finish a quest, the next act appears like randomly. Like for example the IG appearing in orks campaign, or the enslavers assaulting the IG bases... It almost ruined my game because I had no way to know when and where they will appear. Maybe I am missing something. If not maybe a turn counter could be added, and the quests with could be a little easier, because with the firepower required all IA could be wiped out easily, so what's the point in doing campaign?
What I'd like to see :
-For Khaine's sake bring the eldar. My most favourite race

-A world conquest map, like the war for the ring in battle for middle earth.
-Alternative quests just to get some rewards throughout a game.
-Make subfactions (like chapters for SM) for every race with advantages/disadvantages...
