Hello to everyone except those who aren't my friend.
Before we dive into the patch changes, a quick PSA-- patch 10.4 will not be going live until February 20 due to the holidays!
In this patch, we're breaking top Sona and Soraka since they're grossly overpowered in the lane. Additionally, we're making larger changes to the jungle champion pool and giving some traditionally non-jungler champions better tools to do so if they want. This way, we're diversifying the arguably small champion pool for veteran and new players. And finally, we're making Aphelios a little easier to understand not just for the person playing him, but for his opponents too.
