There's a lotta good options, pros will probably overall lean into Viper/Cypher/Yoru/Omen/Scans but there's also a lot of chance to cook for double sentinel, double scan initiator, Neon/Raze/Waylay + Yoru/Pheonix double duelist.
I think it's probably gonna be a bit like modern sunset where double senti and initiator look the strongest overall but everyone plays Viper instead for no reason but i do at least think Viper is actually good and not cope here, unlike sunset, even if she's probably not the strongest option for most teams; who should be leaning into their strengths.
For example, the top 4 of Toronto SHOULD be playing 4 entirely different styles of comps to their strengths on the map: PRX on Raze/Yoru built around Jingg and Something, FNC on Chamber/Vyse for Alfajer and Chronicle, WOL with Spring on Viper, G2 Fade + Sova/Tejo with Jonahp and Trent.
