I'm mostly neutral towards Anemone. I like the lightning and thunder motif and out of the various skill animations I can access they all at least look like they should hurt a lot. I'm not exactly a fan of Annie having this many versions though; if you get dupes of two of those versions you can plug them into a second squad then use the Housewife and Maid skins to have seven different looking Annies.

In terms of new versions I'd rather see more for the lower rank Knights, ideally as part of an event like #69 (The Autobiography of Past and Future, which included 5* versions of Mint, Nymphaea and Di Yu).
