There is possibility shaz will play skye while tenz back on jett and sick on raze. Dapr on cypher/kj and zombs on astra.
there are a few teams doing it, but they really aren't that successful. the best way to run fracture is with viper and astra, 100%, and if i had to guess every team who makes playoffs at champions and plays fracture will run them both, or maybe a small chance one team plays the more aggressive style with 2x duelist and solo smokes astra, but viper on her own is surprisingly bad on this map, i'm really not sure how it caught on to be the meta in ranked
