I can clarify here - The super short version is that it takes a surprisingly long time to make unique champion-specific story adventures, multiple times longer than the rest of the champion. I think it's absolutely worth the time (and they're a lot of fun to make) but there are other things that are even more impactful.
After all, champion-specific story adventures can only be played by one champion, if we can put the same amount of time into making multiple new champions or adding a new adventure every champion can play, it has a much bigger impact in the short term.
