[2021] Riot policy about forgotten champions like Taliyah, why can't she just be a mid laner?

Important: Taliyah mid isn't balanced around jungle, it's balanced around Taliyah mid (her winrate there is incredibly high and has been for years).

Ill say this first since it always comes up but- its clear winrate is not the only important stat when evaluating a champion. With that being said it is a huge limiting factor in what we can do. Taliyah's winrate is already in a spot where there is not a lot we can do with her to give her satisfaction without giving her power. We did the closest we could in opening her back up to being a jungler earlier this year, where as before she was only a mid laner and even more unpopular than she is now. Opening her up to jungler gave her a boost in playrate and it seems Taliyah players overall enjoy her more in the jungle for a variety of reasons. Beyond, the champion is unfortunately just genuinely unpopular. This could be for a variety of reasons, but the fact remains true. We have tried small changes to solve it but couldn't get anything to stick. I think at this point its clear to get a big increase in pick rate she would require some large-scale work which is difficult to find time for, but not out of the question.

Swain is in a pretty similar spot as Taliyah. Very unpopular but one of the highest winrates in the game so that limits us on what we can do. Likely would also need larger-scope work to have a chance at making significant pickrate and satisfaction gains.

We have tried Irelia and Xin-Zhao esque reworks to her in the part but they haven't found as much success unfortunately. I agree they do need something its just a matter of finding the time and resources.
