I don't think it's a good idea for taking luck-3 for some of the nations. If it has not been changed, you still cannot get national heroes with luck less than -1.

For some nations, the heroes are very significant.
Among our old friends, R'lyeh gets the Aboleth and the other mage and Jotun gets the Great Hag.

An extreme example is Tien Chi, all three national heroes are *immortal* mages. One of them can even heal afflictions. With them or without them can make a big difference to your game.
