Nautilus and Varus's new lores are terrible
A while back when a comic was released for Nami that revealed (Or changed) that the dark evil that was threatening her people was the Void entering Runeterra through the ocean, I made comments that I didn't like this kind of streamlining to stories and characters where instead of lots of different people with different backstories and problems, we end up with people with very similar problems.
Here's Nautilus and Varus's new lore.

All know the tales; all pay the Bilgewater tithe. Since time immemorial, Nautilus has roamed the dark waters off the coast of the Blue Flame Isles, dragging impious sailors to their doom. The armored goliath strikes without warning, his inexorable footfalls churning the waters, before swinging his enormous anchor upward to shatter mast and keel alike. He then pulls the flotsam beneath the waves to appease the wrath of the Bearded Lady.

One of the ancient race of darkin, Varus was a deadly killer who loved to torment his foes, driving them almost to insanity before delivering the killing arrow. He was imprisoned at the end of the Darkin War, but escaped centuries later in the remade flesh of two Ionian hunters—they had unwittingly released him, cursed to bear the bow containing his bound essence. Varus now seeks out those who trapped him in order to enact his brutal vengeance, but the mortals' souls within him still resist every step of the way.
Instead of being a tortured soul that had been left to die by his fellow crew only to come back for revenge only to find there was no one left to enact it on, Nautilus is now just a boogeyman, no character, no backstory, he's just a force of nature.
Varus's the worst though. No longer does he have a tragic backstory of his family dying and him being out for revenge at any cost, he's now just another generic Darkin and his host (hosts?) are just two nobody hunters.
Characters are being streamlined so they can fit into a few little boxes of, this person's a demon, this is a Void, this is a Demacian. This is what happens when people try to unify everything into one nice and simple box. What's the point of changing the lore of Varus if he's now just Thresh Lite? If the new lore destroys any kind of characterization he has then what's the point?
Riot needs to stop this new trend of trying to simplify all their champions to fit into specific little niches. Everything doesn't need to connect to everything else and even if it does, it doesn't need to hit the same notes as everything else.
