No Chamber for him in both maps !!!
shahz on jett "could" work, but the comp has no info gathering asides from a cypher trip to watch your flank, on a map like haven, with three sites and long rotations you don't want to play like that imo. Kayo solo initiator doesn't cut it, most teams play double initiator or at worst one of sova / fade, and having tenz on chamber and then dapr on kj / cypher is overkill
