Neon + Chamber would be a great pick on Fracture. What do you think?
Viper Breach and Raze are enough to dominate on attack taking site and planting. Cypher and Chamber can hold prevent retake quite awesomely, specially if the comms are good.
Cypher and Chamber each hold a site and Viper stays with Cypher while Breach stays with Chamber. Raze kinda keeps rotating between sites through spawn and try to stay alive for retakes. If Viper and Cypher have to retake, they can do a passive planned retake. If Breach and Chamber have to retake, they do an aggressive one.
Hope this clears all your doubts with this comp
