I don't know that I'd call it a bug, I think it's just a balance issue. When lower amounts are better, you don't have diminishing returns on adding more points, unlike all the other attributes. We either need more breakpoints, a bigger increase in the cost of maintenance percentage points, or better yet, the option to scale costs instead of using breakpoints, which I think suck as a general rule.
I also wonder if it'd be better to give more points the lower you set an attribute, not less. If I lower trade from 100% to 80%, I've cut my trade by 20%, and get 500 points. Lower it again from 80% to 50%, and I've now cut trade by 37.5% and get 300 points. Why is this so common in games? All it does is encourage people not to pick the extremes. If people would be picking extremes more without the diminishing returns, then I'd have to say the attributes aren't balanced well enough, or the base costs for an attribute should be changed more. Am I missing some basic concept here?
