I agree. There never any doubt in my mind that this wouldn’t be about EVERYONE, not just Carol.
I think they might have messed up her marketting by putting her inbetween IW and Endgame, because a lot of casuals may be thinking she’s just going to be overpowered and hand Thanos his ass.
I can see Thanos having to be more aggressive when fighting Carol - sort of how he was when the Titan-Team got the drop on him and he was reactionary.
I’m sure she’ll get her licks in, as will everyone.
