Yea the kuriotates are awful because the ai cannot handle their special city abilitys. On a wild world like this they dont stand a chance. The calabim do very poorly in all 4-5 games i have played yet, the malakim crush them, they dont expand fast enough and end up sorrounded by the malakim. As a player of course i know that problem and simply settle on the northwestern coast to block them and move southwards then. When i have OV i rush them with 4+ drown and take their eastern settlement, make peace and repeat the procedure. Once they have vampires noone can stop them anyways.
The ljosfalar dont have problems at all, water to the north mountains to the south and lots of space to settle, plus the svatalar are not strong and are hindered in expansion in the west and the malakim come up from the south.
Just dont try raging barbarians and barbarian world, i did very well but kuriotate, doviello, amurites are about to die due to massive barbarian attacks
If you weaken the calabim take some malakim food as well, but add some resources to the west and south, especially that dry half isle to the south of the calabim that stretches from the east to the west is so barren even the barbs rarely settle there

I know you want to have the world willd and harsh but the ai is not as smart as a player is

Strangely i never had the red dragon yet, although i encountered some barbarian settlements.
The luchiurp are squeezed between hippus and balseraph, sometimes they get beaten, sometimes those three sit around drinking tea. Clan is fine, Bannor too, Sidar usually rank top as do hippus thanks to the leaders financial trait. (i wish the lanun had hannah

) The rest is doing so lala, i have yet to find a proper game setting though.
