The Russo Brothers said Shuri is the smartest person in the MCU movies not in the comics. Shuri is nowhere near the top in the comics.
I think you should relax, you don't know that T'Challa isn't in this movie. In fact, if I were betting -- I would say he is. It's just a trailer. The focus was on the original avengers + antman who is most likely pivotal to the plot due to the quantum realm.
I'm just saying it would have been silly for them to reveal that all those characters are alive during the first trailer, and I don't have a problem with where the focus was. Now if you'd like to argue that War Machine should have been an original Avenger, I'm listening.
I'm optimistic. I hope it doesn't have unnecessary stupid elements like Capt. Marvel and Black Panther had.
Havent seen Captain Marvel yet and really not all that excited to but will eventually. This trailer looks good. Looks like Thor and Cap. Marvel will carry a huge load and the rest are going on a rescue mission to recoup Tony.
