I was contemplating this the other day. When I was complaining about this launching with an unfinished story.
PoE's story start to malachai/beast is fantastic. it has a perfect start. Peity, etc all keeps you in it, and everything builds up to the end. After that however.. ooph. Sin, and the beast retcon is blatantly tacked on. Kitava tacked on. They didnt' even bother to go insert any mention of this stuff into the acts 1-5 story anywhere so its not so much of a blatent retcon to the story. since 6-10 was done at once, that all does at least fit together itself... kindof. its blatantly an excuse to return to previous areas.
Atziri would have been a solid final boss. not sure why they didn't go with that. instead we at first got guardians/elder, and multivere madness. ok. then that gets retconned many times.
sirioius shit is completely retarded and lame, and again also completely tacked on.
Abyss, beyond, and other leagues having no relations to each other, and leaving no real marks on the land outside of the league. like, if we saw abyssal cultists outside of the league, ok. great. this is where prophecy and hinekora stuff works. Tied to the karui gods, these are characters we do hear of and talk to/about outside of the leagues.
D3 and 4.put way more focus on "story". I don't check out the d4 threads. but d3's story was so pants on head retarded, it hurt the game. which is again, because they put focus on it.
Poe's not really FOCUSED on the story, even in the first place. and then its opening story is then also fantastic.
Last epoch story... is incoherent on every level. even if you ignore the time travel and multiverse.
