Alright, I'll concede with most points, Kadaeux. However,
But if that is the case, well, then we have a completely different problem to assess. Because voters shouldn't be doing that.
While I see your point, I unfortunately doubt that a title change for the Casual/Advanced split will ever become a reality. The suggested one especially, since the Casual/Advanced split stands for more than just word count.If a change needs to be made don't change the difficulties. Change their titles.
Change Casual to "Short Story" and Advanced to "Story" or something similar.
