It seems crazy, but playing double sentinel instead of kay/o with Jett, Sova, Cypher, Omen, Killjoy is a very strong team comp. I've used it in Premier and HSEL and haven't lost a game with it. Kinda shocked no teams have atleast tried it.
Depends on how you play it. It allows for lurks up market and cat and a lot of information on attack. My team was always better on attack, so locking down on defense really helped us
