I finally gave a spin to Chaos. Is there any point in kicking around the Norscans but exp and loot? It seems that the awakened tribes just start fighting each other, forcing you to choose between them... which is pretty stupid. They should become vassals and vassals should be unable to fight each other. Any mods fixing this? I'm not surprised that a Total War sucks regarding diplomacy and such, tho. It is weird how no matter how many iterations of the game we have, CA is totally unable to make it even work in a basic way.
The Chaos early campaign sucks super ultra dick. I usually just autoresolve most of it.
What you want to do is make enough for a sizable army of warriors or Chosen, and then go roflstomp through Kislev and the Empire. It's way, way way more fun. Fighting the goddamn horse skirmishers of Norsca is ultra boring.
I never really bother awakening tribes either. It's a waste of time.
If there's any mods I'd recommend for Chaos campaign, I'd get the one that removes horde infighting. It's just stupid. Also get the one that gives Chaos rifts a passive Chaos corruption spread.
As for the campaign itself, I recommend you completely skip the marauder line of garbage and go straight for Warriors. Hell, just straight up delete your marauder building so you get more growth and money.
This is one of the reasons why I said Sigvald and Kemmler are way more powerful than their stats would suggest. Because their starting units are so much better. Sigvald starts with two Chosen and a Hellcannon. Heck, you don't even need to wait for sieges with him as you can attack straight away. And every single battle involves the enemy coming to you instead of you having to go to them (super important versus Norsca). Chosen roflstomp everything. Sigvald himself can just waltz into combat and just cleanse the filth no problem.
With the other two you kinda need to farm for better units and the hellcannon.
