The phases should have had some connected story

The MCU should have had connected storylines in the later phases after most heroes where established. I imagine it with how the big crossover events in comic worked with the big main comics and tie in comics in each series. A phase should have started with one crossover movie, have several connected movies for several of the others ones, and then one big end of phase movie bringing the phase to a end.

I imagine it like Infinity war as a phase starting with infinty war, ending with the snap. And then some movies where you see what happened in between and what the snap had for consequences in the world like how some villains used the consequences of the snap to do crime or how in Wakanda it had consequences for the country. Then Endgame only at the end of a phase.
