Pillage bonus sounds good. As for sailing,.. most of the marauder tribes are land based, up in the extreme north around the chaos gate at the pole. Only the norse just north of the old world seem that interested in sailing.

I think Chosen should be sacreds, yeah. Chaos are a pretty religious nation all things considered, since the Four Powers are a part of every day life.

Technically, Chaos should get a Chaos Warrior Chariot and a marauder chariot. I think just the chaos warrior one would be fine. As for cultists,.. I say leave them. That was the old chaos before they brought in the idea of the northern lands being rife with tribes of excellent fighters rather than fodder humans.

I think Knights are a must for Chaos. If you have trouble drawing horses, just use a horse sprite from the game as a base - the sprites were made available by K O recently, including attack sprites, so just find a random cavalry unit from there and heavily modify it to get a nice chaos steed (with extra powerful hoof attack).

I guess the 2 big weaknesses of chaos are the high cost of their stuff (if you leave out cultists) and their lack of missile weapons. This translates fairly well into dom3 I think.
