An earlier description of patch 13.6 in LoL. All the nerfs, buffs and other changes in League of Legends

What exactly will change in the next League of Legends patch?
The previous League of Legends patch received a lot of attention among players largely due to the release of Yuumi’s refreshed skill set. Skillset turned out to be really strong – although players don’t necessarily like the refreshed heroine, she is doing really well. Riot was forced to release her hotfixes, and more weaknesses are coming in the upcoming patch.
In addition to them, the roster of updates includes fixes for other heroes – including the recently refreshed Aurelion Sol. What exactly is coming to League of Legends in patch 13.6?
