The likelihood that our labels are going a makeover is slim. The general idea is that we have a good system of expectations outlined and should a GM need to personally tweak it for his/her RP, they're free to do so. Free, Casual and Advanced have a noticeable gap to figure out where someone is. The idea of "High Casual" may just stir up debates as it has in the past with people trying to find a middle ground between the three we have now. If we kept changing them, it might only confuse people and cause more bias between writers. ("High Free/High Casual" etc. is used by some now, but adding it may just make more issues)
