I'd like to think that Brandon wouldn't always be so predictable as to pair off his superpowerful cosmic beings.
Well maybe it's not in super obvious ways for all of them; I prefer patterns to just random shards surreptitiously placed in each world. Again with the whole Inuyasha thing, they keep searching for shards in random monsters, there is no rhyme or reason to it and that drives me insane!
And Brandon’s magic systems always run on rhyme, reason, and patterns. They’re never omniscient and all powerful like Gandalf, Dumbledore (in the movies), and Superman.
And I like that there are limitations, it makes the books so much more... palpable? (that may not be the word I'm looking for but it's all I can think of 8:46 am)
