I'd prioritize Wanda over Erik. She hasn't had as much focus in the MCU until recently, whereas he's had several XCU films. Plus I think her fans are right about the connection to Magneto. It doesn't help her and I don't want it in the MCU
I don't think either group of fans should be tribal, tbh
I'd say BW doesn't have much solo material, but then again Shang-Chi doesn't either, so both can get solo movies. Frankly it annoyed me in the first Avengers how the only female hero wasn't actually a superhero, and we had to wait until AoU for one, and then Ant-Man where Janet is fridged and replaced by Hope who isn't allowed to be a hero in that or Civil War. That's kinda why I didn't like Ant-Man 1 anyway.
As for Hawkeye I agree. Although isn't Clint old enough to be her dad in the comics? If he's about Wanda's age, and she has adult sons the same age as Kate, right?
