what is the best composition for fracture?

I think a comp with viper, Jett, breach/skye, kj, and maybe sage is good. what do u guys think?

Viper
Raze
Skye
Kill joy
Sage

From what I've observed, any controller works but viper has very easy to do executes with her wall. Cypher's ridiculously good on this map because of how the defenders will inevitably flank you + busted one ways from drop stalls attackers really well. And then you can pick up your initiator(s) of choice + Jett/Raze, or even throw Sage into the mix.

viper, brimstone, jett, skye and cypher.
there si much intel to gather and few good KJ ultimates (u can wallbang the tunnel ones) so Cypher > KJ also there are many early round fights so having 2 controller is good, brim ultimate is OP in postplants

Viper Brimstone Kayo Sova Killjoy

Cypher is a good picm, especially holding B.
Omen can work around with his smokes on A.
Jett or Raze can shake things up very easily with how the sites are set up.
Sage's wall can either deny either entry easily, but I like to deny B Tower and A satellite respectively.
Sova as a gadget agent.

-Kj
-Cypher
-Skye
-Astra
-Sova
2 sentinels no duelist meta trust me
