Yeah, we need to give them wiggle room so they're not bothered about consistency.
The thing is, telling stories on such a cosmic level they're trying only works if you keep it vague and mysterious and simply let the people speculate about it. These stories also depend on very solid world building and consistency, if these don't exist the story degenerates fast into a pile of nonsense, which can damage the whole fantasy universe than that it is helpful or interesting. Dungeons and Dragons does a decent job at this in my opinion, but they have better authors and even they keep a lot of stuff about the gods and their planes quite vague and mysterious. Blizzard, as with WoD and their idiotic take on time travel, is again biting off more than they can chew.
