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.

These buffs, plus the Immolate changes (spoiler alert!) in 10.4 should help Amumu as he tries to play with the big boys.

newSTOP! IN THE NAME OF LOVE Now stops enemies in the middle of their dashes
[Aphelios](http://gameinfo.na.leagueoflegends.com/en/game-info/champions/aphelios/)
Players can now see both of Aphelios' guns. Calibrum no longer resets basic attack timer after consuming a mark. Crescendum sentries die faster. R range decreased.
Aphelios is the galaxy brain marksman whose kit has a billion things you have to learn, but he's stressing out opponents who can't understand what he's doing and seems to be lacking adequate counter play at higher ranked games. Better clarity will lead to a drop in Aphelios' performance since opponents will more frequently make correct decisions, but we also threw some raw nerfs with a focus on making sure opponents have successf
