Having actually looked over the frame data, I think she may have been nerfed since the Kombat Kast. It has f2 as 17 frames and it looked more like 10 before. She has a noticeable lack of plus frames and mids, but a totally safe low and a mostly safe overhead to make up for it. Strings into puddle might be the world's best gimmick again though, so we'll see.
A little concerned that she might be a character that needs to get a hit to actually start doing most of the stuff that makes her shine. When I think of D'vorah, I think of pressure and setups. Going purely by the frames I am presented, not hitboxes or anything else, I don't feel like I'm looking at a pressure character, and I don't have my hands on her yet, so I can't be sure how effective her setups are. I'm assuming oppressive as hell, but I tend toward pessimism and I don't have the full picture right now.
Also, the normals added with Parasite aren't in the frame data, so that could give her better strings, or even explain why F2 was so fast in the Kombat Kast and isn't now.
