About kay/o, they are setting a precedent of using kay/o in icebox and breeze, so it is possible to say that they are creating a new meta. About breach, it was already known that breach is good in split, is just that nowadays nobody picks him
i think for the way c9 was running the comp, where they played back and did fast retakes, it makes sense if you know that the other team is playing viper to run both breach and skye. i wish we'd been able to see how they planned on running offense rounds with that comp
