League of Legends patch 25.17 is fairly light on balance all the things which will be considered, but there are interesting trends across the notes: it is aiming to make several champions who cannot jungle viable in the role.
Historically, when the champions who are not meant to be in the jungle got buffed up to be able to kill camps efficiently and it has been meta meta-defining affair. The three aforementioned champions have a lot of time in the pro play after the buffs, so there are subsequent nerfs which were unavoidable.
The champions Riot, which have chosen to make viable in the jungle which are certainly interesting at the moment. It is not super clear and now viable Vayne and Nilah, which will be in the role, but they are at least playable.
