Honestly, i could see something like Raze, Harbor/Viper, Omen, Cypher and Gekko.

Raze is still the best duelist, and the nerfs won't do too much to her on this map.
Harbor/Viper is necessary, with teams having to decide whether they want to go for a defensive comp with Viper or offensive one with Harbor.
Omen is one of the best agents in the game right now, and his tps have insane outplay potential.
Cypher is the best sentinel in the game, and I can see his cam have a lot more potential then KJ turret, especially with there being so much potential for unusuall placements. I could see a triple controller comp with Astra instead of him, but I don't think that's a good choice.
Gekko will be insane when it comes to not only plants, but also the number of fights there is going to happen. His util regening so quickly will be too op to not pick him.
