Hi.
This patch, we're addressing the "zero-CS-top-lane" problem in a more systematic way to squash similar situations in the future. Sona and Soraka were just the tip of the iceberg of the hypothetical "zero-CS-top-lane" playstyle, so we're making larger changes to the top lane that should remove such strategies from showing up in the future while also allowing games to be carried by those in that lane. Current pro play mainstays Ornn and Sett are also seeing some nerfs so that we're not constantly seeing folks getting rammed down and thrown around by these beefy dudes. We also have a second round of jungle champion changes to help slightly widen that pool.
We also got some ARAM balance changes, as well as the initial release of Eternals! Like other features and content outside of Summoner's Rift, these types of content might not be for you and that's okay. So just do you. Play ARAM, try out Eternals, purchase skins-- or don't!
Take this portal if you're looking for TFT's patch notes!
