I’m a little disappointed about that too honestly. Also, the characters from the TV shows should have been there. I don’t care if they had no setup. It would have been cool as hell to see Ghost Rider, The Inhumans, The Defenders, and The Punisher there helping out.
I'll admit, I'm a bit disappointed they didn't bring Quicksilver back too. Like, I get it, he's dead, his death is a big part of Wanda's backstory, but like, imagine if someone like Hawkeye or Cap was about to get their **** rocked by a bunch of Thanos goons, then suddenly a blur zips by them and knocks all the goons flat on their ass. Then, the camera pans up, and we hear that classic catchphrase:
"You didn't see that coming?"
