But arent worlds using earlier patches than currently available one?
Nope, the Worlds Patch is hitting in the next one or two Patches and this is the one they will play on.
Riot still starts buffing Champs they want to see in Worlds earlier (as you can see on the little slap on the wrist Kai'Sa [we swear she is hard nerfed, what, you want five Movementspeed taken away also???], Lee Sin and Eve Buffs etc. More to come).
Also, Tournament Skins are avaible when the Worlds start, so that explains the needles Kha Buff, possibly more Kai'Sa Buffs, because she was sooo hard nerfed, just like Riven and will get maybe a G2 Skin this year (because they will win :3).
Count that together and you can mostly pinpoint which Champs will get Buffs etc.
