If I recall correctly, Acken nerfed Range HP, and maybe Damage done, and beefed Melee. You couldn't just smack down a city with 3-4-5 Range and then walk in with one Melee/Horse. The 5 AI really seemed to "understand" the mod. Again, IIRC, city strength was lowered quite a lot. So on defense you needed to park some Melee out front, you couldn't just casually focus fire and let them kill themselves against the city. He also did a lot of other enhancements. It quite surprises me that his (and other balance mods) didn't get more consideration from the 6 devs. Acken Deity was almost unbeatable, and not just from insane AI bonuses - the AI was just plain mean.
