Okay, if that's how you view it, then it's pretty sad. But what you are talking about isn't complexity or originality, it's utility. Yes, a porcupine effect DOES have more utility, but ultimately, for a tanking effect, it's not original at all. It's been done, many times, and even in this game with Vengeance. Complexity refers to how a skill works. What is its effects? Does it just do one thing? Two things? Three? Or does it continually evolve and change depending on the situation? Does it have a stronger potency when there is more damage, and less when there is less damage? Does it evolve? THAT is complexity. Originality refers to how common is the skill. Has it already been seen before like the porcupine effect, or is it something unique to the game like a shield based on damage taken from the previous hit?

What you are talking about isn't complex or original. It's flat and has already been seen in this game. Further, I know what stance dancing is. I heal as a Scholar, and use it. I was doing it back when Paladin was the only class with an off tanking stance, and still do it now that Warrior does. There is a huge difference between stance dancing, and just dropping your tank buff while you're the main tank. The former is intelligent, the latter is stupidity. Don't perceive to educate me. I know what it is, but I didn't mention stance dancing did I? I never said stance dancing was dumb. But I suppose that is my fault for not clarifying. Allow me to do so. Tanks that drop out of their tank stances while main tanking are idiots.
