Chronicle cosmology must be erased. Kabbalah for kindergarteners is a popular pastime among worldbuilders, and I never found it interesting, Warcraft isn't an exception. It's so sterile and tidy that it completely lacks life and vividness. Yellow magic makes you X, purple magic makes you Y... Ugh. I wish people could experience profound emotions because of themselves and not because of being irradiated by colorful rays and make mistakes because of reasons they find themselves in and not because straying away from enlightened centrism makes you bad. It kills potential for religion lore because it quickly boils down to colorful rays you must balance like an accounting department. Priest order hall is one of the worst takes on religion I've ever seen: the authors love their kindergarten kabbalah and have no idea what religion is and how it works for good and for bad.

This "saga"? I'm very subjective, and I dislike it. The story revolves around a few chosen characters, and the world bends and twists around these characters to accommodate their story. Elf reunification raises so many questions because there are many matters the devs have no wish to address even with a single line, Anduin's story makes me sick with how the world is accepting for someone it'd see as a man who derelicts his duty because of purely self-centered reasons, and Xal'atath is an archetype of a villain instead of a villain, so all she does is floating around as a sexy elf cackling and throwing intimidating quotes, but there's nothing eldritch about her and nothing concrete about her goals, she's just there because the story needs an antagonist (which should be marketable). It all is clearly not for me, so I'd cut it in a heartbeat. I don't think it contributes something great to the setting or elaborates old concepts in a good fashion.
