One point; the human's bonus feats in E6 go from being amazing to being... meh. I think that the humans are balanced with the other races. They get +4 to two skills and two feats, as well as a few other things. Compare with Orcs. Orcs get a rage, +2 to fort, and +2 to two different skills, as well as being very hard to kill. They seem to be of equal balance. Elves get a +2 to three skills, a 1/day +10 to something, boni against enchantments, and ability to get past concealment somewhat. So the humans have more skills and feats, while the other races get actual abilities. I don't see an issue.

This is what I meant by comparing all the options at the same time; as long as the power is consistent inside the system, who cares how it compares to a Monk or Fighter?
