It's this attraction I'm referencing. It was initially thought to be a coaster, but I think a few people pipped up that it was more RotR styled.
@GiveMeTheMusic perhaps?
The entire HK buildout is the Shanghai apology tour. From a bigger castle, to a sorry your version of buzz sucked here's a new one, to sorry your Fantasyland sucks here's more attractions. The Marvel attraction is the sorry you don't have an epically scaled E-ticket like Shanghai Pirates.
I don't think AntMan will be underwhelming. Shanghai's Buzz is actually a very good iteration and this seems to borrow heavily. It's still a D-ticket and still a shooter attraction, maybe that's its downfall amongst opinions.
In terms of DCA I don't think we'll get the immersion with the current crop of characters. The only thing I would find immersive is Wakanda, as you mentioned. That said, while we have the aesthetic of the Spiderman attraction, we actually have yet to see anything of the land itself.
