I disagree, nobody said Peter is not Spider-Man anymore, he's featured on the all new all different marvel teaser image as Spidey, we just don't know if he'll have his own title (which he'll probably have), Falcon is perfect as cap, he really did own up to the role and Steve is also around but just not as cap and the new Thor is also an interesting, well written character, and once again the old Thor is still around. The Fantastic four will appear on diffent teams, just not as a whole, which is fine they're allowed to take a break. Marvel is doing a lot of great, fun, well written books lately but the problem is people just can't seem to accept change even when it's good, or they just don't give it a chance all together. Have even read the new Cap and Thor books, and Ultimate Spider-Man with Miles? If you did and didn't enjoy it then that's fine, don't read them and go buy Unbeatable Squirrel girl, Howard the Duck, Ms. Marvel, Silk, Spider-Gwen or Silver Surfer among some, but if you haven't read it then you can't criticize it.
Also you only mentioned Marvel so even if you don't like what they're doing right now their is other stuff you can read, maybe try some Image.
