User blog comment:ClariS/AD has Diminishing Returns!!/@comment-5284325-20120828134118/@comment-4881935-20120828170523

no it's not. Diminishing returns is claiming that you get progressively smaller rises in output resulting from the increased application of a variable input. In other words, it just means, if you buy more in one stat, the less you get out of it. That is nowhere the case for AD.

All you are saying is that because other stats become more valuable, you want to buy less AD, but this doesn't change the fact that AD remains at the same usefulness. Because the value of AD remains the same, there is no such thing as diminishing returns.
