Meh. I played Demo on beta, got pissed, saw the Simcraft, got more pissed, posted it so people could be pissed with me and got loads of QQ.
I'm not an idiot, I know that the graph doesn't really say much, but I really felt like Demo on beta was just dull, and that's the point I was trying to make with the graph.
My main issue was how boring Demo was in Meta too. Either way, they added 2 new spells since I made this, so I was kind of right (in an annoying way, I'm sure).
EDIT: Also, the second graph that has been posted has almost an extra quarter taken up by things that don't exist on the first one. Deduce what you like.
