[2021] Vi and Xayah Hotfixes Inc

Lethality Xayah and Vi were both breaking 55% winrates (with Xayah outperforming Vi).

These characters were pretty wildly out of line and waiting another patch would've caused a lot of messed up games, especially at the end of the ranked season.

While I understand the Camille frustration (and personally am frustrated playing vs her) she's not the same degree of powerful right now.

She's the kind of character we would address in a normal patch (though likely not next patch since that's preseason and not a balance patch)

We tend to hotfix for either absurd winrates or egregious bugs yeah.

There was a bug this patch that yuumi could be permanently invisible if she jumped off of an ally who was eaten by TK that had to be hotfixed for example.

Important to note that Xayah was 57% nearing 58 and Vi was nearing 56%

Its a bit above our comfort level. This is also the last patch of the season so we would rather not ruin the end of season climb with secret OP builds being discovered in the final week or two.
