Now that we can talk about the trailer (no longer leaked). I did a similar threat when the leak happened but it got deleted (i can understand why).
Full chaos corruption - In the trailer a Kislev generals gets corrupted by Chaos (as it should). I hope this means chaos corruption gets fully reworked because as it is now it's just anti-player = because the AI get bonuses...
But with this rework we can see the real chaos - corruption.
1 of the main theme in WH lore is corruption. I was really sad since warhammer 1 that humans can't be corrupted by chaos just with corruption.
Humans can be corrupted (all humans races). Elfs = slaanesh (or dark elfs = they are already corrupted if you ask me but this is not the main topic). Orcs but is really really really rare. Ogres (there are indeed chaos ogres).
Khorne units look really cool. Damn this got me so hyped about Khorne. I was aways a fan of Khorne but I also had some hype for Kislev but now(as a slav myself) ... Now I'm all in Khorne.
Chosen of khorne look better than the teaser (hopefully they will look like that ingame too)
The lady with the bear - I think this is just a generic general for Kislev. Thou it might be a LL.
the bear I think it symbolizes Ursun = Ursun is the dying god. She need to help Ursun.
Flying bloodthirster ?! Maybe . Maybe !
The tower at the end. I think this is a settlement captured/corrupted by chaos or a Khorne fortress in the chaos wastes. It's too small for the Brass Citadel and too normal looking. Also damn khorne looks awesome !
And it makes no sense if khorne is that big his citadel to be so small
Maybe this mean chaos can capture citys (if it's a captured city) or the better case (for me) chaos can capture only some citys and make them into fortresses (brass keep) + chaos wastes and Realms of chaos.
Another reason I think this is not the brass citadel - it's too normal for this to be RoC (the area around it is too normal) - it looks more like the chaos wastes from vermintide 2. Also it makes no sense for her to run in a forest then a forest on fire and after that BAM Khorne citadel, it's not RoC.
I can't wait to see the other gods !!!
Anyway I just wanted to gush over the trailer... Thou feel free to tell me if you agree or disagree with the points I made.
