I don't consider Rock an A-list actor but he may get there this year: 5 movies, 1 TV show, WWE champ... He's having his best year ever.
There is nothing wrong with this...guy had a LONG string of films that came into #1 or 2 opening week for years.
Like if you put Rock with Kate Beckinsale..who gets top billing? Rock kind of has no problem doing whatever the role that best suits him...like in the Other Guys with Sam Jackson. Just how he is.
that his show is on TNT? How could he not get his show on a major network? TNT is nice, but he should have been on CBS or ABC with that show.
The dude is everywhere. 

they refuse to hear anything but he's top box office
... If you can get a movie made just by attaching your name that's what makes your a-list really as of now rock can't do that
