Probably nonsense but it makes sense.

It has really felt to me that only NWH, MoM and Loki really played major parts in the whole Multiverse story.

The rest were setting up new characters. Apart from a couple of short scenes this saga has not existed. To me it almost feels like the last few phases were teasing it and that Doomsday / Secret Wars feels like the actual launch of things rather than the end.
