Could we make worlds specific patches?
The Gangplank/Azir/Shen nerfs for instance are obviously not for solo players and for the common man, these nerfs are going to hurt. We don't have the drive, we don't have the skill, and (most likely) we don't have full teams to coordinate plays with Like in worlds.
I get that GP and Shen have strong, low interaction ults, but if you nerf them it's going to hurt solo players an unnecessary amount. Azir for instance used to be good in solo matching, but his performance is abysmal due to the "pro" scene. Due to his maximum potential being so great, you had to go and ruin it for everyone else.
My proposal as it stands right now, would make worlds specific changes/patches. They already operate on a separate version of the game, so why not only apply certain patches to that? (For instance the Shen nerf) This way you can still handicap the pros without murdering a champions solo performance. Just something I thought of in the shower.
