Sorry not to respond to everything due to time - I do think you make a lot of good and thoughtful points, especially the last one, and I'm sorry I can't reply to them all adequately. But this one in particular is interesting (at risk of being off-topic).
I personally think the contents of the P2W vendors should find more organic places in the world and have their stock also balanced against what's reasonable to earn and how they fit in with the rest of the game. I think it's done a very good job of bridging the gap between live's store and homecoming and shouldn't go away until all its contents can be acquired elsewhere, but I do think it needs to find a better fit place in the world. (For instance, I would prefer to see Ninja Run/Beast Run be alternative customisations for some powers rather than their own power, and speed and jump height is back to being something gained from travel pools. The freerunning power from the utility belt pool would replace their functionality.)
For me, the changes and new features bring these methods of travel into a kind of balance threshold that I expect the game to have. I think other things could also be brought into that threshold, but that's a huge and nuanced conversation to have. I'm sure others will disagree with me, which is fine and it's the nature of adjusting these bits of content.
This might not be on the dev's radar at all, which is fine, but if it was then it would be quite a big job to figure out where things would land. I wouldn't expect it all to happen in one update.
