This varus lore change reminds me of what happened to Xerath.
I remember the days when Xerath had his lore being remade. First he was a sorcerer of a civilization and experimented on powers far beyond his control. And blew it up. He had quite a few ties with people that are now currently deleted.
And after that we had a near 1-month worth of lore streaming in to fill in these gaps. Vizier of the emperor, former slave, back-stabbing schemer, but was always on Azir's side. Until the tragedy that was not meant to happen. That lore change was a success, because Xerath now is a totally understandable, and filled in with conflict and ties with others more than his previous version.
The problem of Varus' new lore, is...it simply lacks the complexity and volume compared to this. Varus was a villager, father, protector, and most a being of fueled with vengeance on "borrowed time". It is good as a story on its own and it is a shame to cast it aside. When I play Varus and hear his dialogue, I had that feeling that NOBODY will stand in your way. Your arrow punching through anything was very symbolic in that term. And that theme of "vengeance" and his loss had me very attached to him.
It's a real shame.
