I feel like there are way too many members on team flash now so I think they should maybe remove some people as we are getting Bart Allen in the 17th episode. Here is who I think they will possibly get rid of.
Frost: Since Kristen Kramer is attempting to arrest Frost, they should maybe have Frost either in prison or have her be on the run which will have Danielle Panabaker play one less character as it's difficult when an actor has to play more than one character in a single scene. Also, there's too many people with powers on the show.
Kamilla Hwang: she literally has no purpose on team Flash, and she's not really a member of Team flash he's more of like a team citizen member. she barely even appears in the show anyways so like I don't know why she's even a member.
Cisco: this is killing me but Cisco have to leave. he barely is doing anything anymore, and he is not vibe so it would make no sense to keep him around he literally just has a replication of his old powers. we also got Chester on the team now.
