With the introduction of fracture, we wil see him more. But I get what you mean, maybe we will see him getting picked more in maps like haven and split
Nope. Nuturn ran Breach on almost every map. Either Solo or Suggest would play Breach.
Their Breach play on Split against Damwon was also famous which took place in Challengers 2 Finals.
Also iirc Stax became Breach main after stage 2.
Kayo Breach on split is something I feel is under explored. I think it could be very strong. Skye Breach has been shown to have some minor success but I think Kayo Breach would play off each other better because just stronger abil spam.
