I addressed the "flop" with my original reply I am in agreement with you that they were wrong too. We don't know either way for certain and also I'm not discounting the effect that Rule of Cool has on the popularity of a subject. I understand what you mean by it feeling sort of guaranteed because we know most people like dragons just like most people like Illidan.
Only reason I replied the way I did is because I get somewhat incensed by what I perceive to be the beginnings of pointless arguments in my threads, often times causing them to get derailed. Which of course I understand the irony of considering I'm involved in a derailing conversation right now! Kek
