My personal take: Duelists who can play both Jett and Raze will thrive in this meta (aspas and derke for example) while jett one tricks who previously played chamber will have to adapt to playing new agents.
Was going to say this. We are in the jett, raze, kj meta. Players who are good at these duelists and players who were good at the sentinel role (like Suygetsu, not chamber players like yay) will thrive in this meta the most. Best candidates for this are Derke and Aspas.
Aspas and Derke. They are likely the most well rounded duelists atm. Can play top level Jett and Raze. Both have similar level if not better Jett than any top Jett while also having Raze that can rival some of the best.
Aspas and it's the largest gap we've seen since TenZ to #2 in Masters 2.
This meta is wayyyyy better for Aspas when he was already the best primary entry in the world, and Riot took away the best piece to counter a primary entry.
Also, Jingg is probably who I'd throw as #2 in situation. Just like Aspas, he's a prime entry that only benifits from not having to deal with a chamber.
