In patch 13.1, we did a large pass on Fighter items in an effort to sharpen each item's choice and generally reduce unneeded Ability Haste. Death's Dance took one of the hardest hits when we introduced these changes. With subsequent changes to Marksmen and Seraph's Embrace/Rod of Ages, Fighters have struggled when on even footing in duels (and especially teamfights) versus classes they once bested. We’re reverting Death's Dance to give fighters slightly more power in elongated fights but still keeping the tradeoffs in reduced haste compared to Black Cleaver and Ravenous Hydra builds.

Catalyst of Aeons, in its current state, is significantly cheaper than Lost Chapter which has turned it into a dual threat. Not only is it the preferable scaling item, but due to the lower cost it has become a better laning phase option than Lost Chapter which seems counterintuitive for a scaling item. This adjustment should help make itemization choices for mid mages a bit more competitive.
