User blog comment:ClariS/AD has Diminishing Returns!!/@comment-5284325-20120828134118/@comment-1619490-20120905100003

I think people are going to have to clarify their definition of output...

In ClariS's case, it seems to be % attack damage increase, which makes sense to be considered diminishing returns.

CDR has diminshing returns because after 40%, you don't get anymore (you might not count that though).

And the value of AD doesn't actually go down; other stats like crit or armor pen will give you a greater damage increase, which is dependent on having higher AD.
