I keep saying that they should totally go back and update a bunch of older league mechanics/loot (talismans, abyss, breach etc.) and not do a "flashback" league or whatever, but make it into a new league focused purely on updating a lot of older content/mechanics so it fits better with the current state of the game.
Because short of a system to de-corrupt Talismans and allow them to get Blight enchants they're gonna remain hot garbage.
