I don't understand what Warcraft has to do with it? Do you disagree that the chaos/rage of the Horde weakens over time?
Don't look for any hidden meaning in this (=
Regarding the topic:
Of course, both chaos and shouts will eventually cease to be the main ways to win. This cannot be said, for example, about the school of light magic - the relevance of "stone skin" and "haste" (and also "punishing strike" and similar spells) is eternal *the same story applies to the opposite of light - dark magic*. Although I consider the school of summoning magic to be somewhat useless - apart from "raising the dead," there is nothing worthwhile there.
