You're missing his point. He's already admitted that there are key errors with Dwarves and Elves, the issue is that we can't do away with/heavily edit the main Descendants at this point now can we? If we could go back in time, yes, changes to better differentiate and create meaningful differences between the races would have been implemented. It is what it is, we can't go back in time sadly. However, we can go forward into the future, and the fact remains that until you provide an addition to this application which will adequately create roleplay in a way that couldn't be replicated by one of the already existing creatures/races, it should stay shelved.
