So at the beginning you have to pick 6 characters, from 20 premade ones, that will help a demon prince destroy the lands of man, dwarf and elfs.
Perfect
The AI has problems with fighting in tight places, sending ranged units close to the melee units and dosnt use skill that often, but it can be tricky on higher difficulties and alot of the missions they keep spamming reinforcements.
The dwarfs have set up a trap for our prince and we have to defend him.
How about you guys keep fighting each other and just let us pass.
They never listen.
Honestly this is my third party, i just play the campaign until i figure out a good tactics and then i restart.
At start you have to grind for levels until you can finish the first missions on extreme difficulty and then just keep replaying them to get biggest gold rewards and buy epic equipment.
