I mean to be fair, Rogue wasn't on the cover, nor was this issue advertised as a Rogue issue. Besides, they're not just putting her on the team for fans to buy it; she's going to play a role on the team, she just has to wait her turn for her spotlight issue, like everyone else.
They're likely going to split the team to tackle Cordyceps Jones. With less characters around, she'll have more of a chance to shine.
