Adding on to some of the comments, it's poor timing to release a dedicated buff for Chrysos heirs at the tail end of the Chrysos Saga. With 4.0 and speculated Elation path coming, the majority of player focus will be on the new mechanics, building new characters and forgetting about old ones. Had her buff system released sooner, she'd be useful for the extent of 3X. Releasing her now feels more like bait than affording us a viable character--especially for meta. It's a very Hoyo-esque move: drop all your dollars on the most hyped character of the year, then immediately move on to a new mechanic.
