Detailed description of patch 12.19 in LoL. Syndra rework, buffs of 8 characters and nerfs

Which heroes will undergo changes in LoL in patch 12.19?
The Riot staff has released the changes in the upcoming update numbered 12.19 for League of Legends. Surprisingly, there are definitely more buffs than nerfs in it, as those received only the low division players’ favorite and the early game queen.
In addition, a sizable makeover was given to the bullet-throwing Syndra. For this reason, it can even be called a small rework. The patch is scheduled to go live on Wednesday, October 5.
