Wow, just wow. One of my most anticipated units and look how they massacred her.
This is basically Archdemon Shadow, but without even the unique debuff:
1- her S2, that would have been at best a niche skill IF it'd negate Tagehels, is completely useless, since it doesn't even do that (EDIT: on the EN stream it was said that she didn't, but there are rumors that it prevents Tagehels, so it's at least useful against some cleave compositions and STene, I guess...but that just makes her another "one trick pony" like Solitaria and look how much she's used at the moment)
2- her AoEs will activate so many counterattacks from Violet and Rem that she'll be a liability, instead of an asset
3- as for the rest, an RNG fest of a kit (the random crit buff on her S2 is particularly cringey)
Also, to add insult to injury, Angel of Light Angelica has just been released, so it's not like they don't know how to create a powerful and versatile kit, this is a deliberate choice.
