I think I'm speaking for a large portion of us by saying that there would be no upset at all in you drawing a line to finish what you have before too many submissions and requests are submitted. After all, as you said, just the surface scratching of black and white is Pandora's box. You've done so much to enhance our game, and with your coming additions, I personally am beyond ecstatic and I know I'm not alone. Thus, do only what you can and draw the line where you will. There are always later versions for coming years ahead.
Your stats make perfect sense and add incredible flavor where it was desperately needed. My players consider them gospel.
Thank you again.
