How are we supposed to get our personal answers from that? A>C, B>C, how does that help to compare A & B? You might as well remove the Lich King bit and you can still say the same.
Additionally, you don't always need a statement from authors to conclude if one character is more (or less) powerful than the other. Otherwise, 99% of those cross-verse battles would never get a conclusion. Sometimes, you can just do that based on what they have done. It'd only be subjective if we can't get a conclusion from their feats, but that doesn't seem to be the case here.
