It's not even that Reed screwed up, necessarily, most of that was true before Secret Wars as well. What's different is that we may be viewing a universe with a predestined future and no way out, rather than the open ended one that Marvel typically follows, where the future can be changed (or more accurately, the focus jumps to a new universe where things were done differently) What might be different is that, at least for the time being, universes no longer fracture when a divergent path comes along naturally, rather they are all created by Reed and Franklin and have fixed futures. A bad one, in this case.
I don't think he needs to be the god of Stories. I think that is overselling the power that comes with that role. But it could be that it plays a part. I just hope it is not in a finger snap, *poof* sort of way, (unless assisted by the Infinity Gems as a temporary powerup) more of a Kid Loki rewriting Cul's story sort of way. That was a big problem i had with the end of Agent of Asgard. While I liked the thematic change, I think it portrayed him as WAAAAAAY too powerful to do anything really interesting with him going forward, he seemed pretty much both omnipotent and omniscient, which is just too much.
As for Loki time travelling... well, only King Loki did that, and I just took that it mean that he had learned some new tricks in between then and now. The only time present Loki was able to do the same (when he killed Laufey) he required Hela's assistance. So no, I don't think jumping around in time is something Loki's going to be able to do very easily.
Anyway, I was listening to some music and after my last post, this jumped out at me as perfect for Loki at the moment:
And I know metal vocals can be hard to understand even if you are into it, (though this one is mostly clean vocals) and I know my tastes probably run a whole lot heavier than most in this thread, so here's the lyrics:

Or maybe.... https://www.youtube.com/watch?v=CxT-NNZMD-k
bonus - Jane Thor: https://www.youtube.com/watch?v=hNRViWBT2gY
This one is almost eerily spot on, (though there are a couple typos in the lyrics on that video. it should be 'no cause to be alarmed' not 'alive' among others. but you get the gist, anyway) but there is a reason for that. It comes from Mastodon's album Emperor of Sand, which is a concept album about fighting a losing battle against cancer, after several of the band members had loved ones go through their own fights with cancer, some successfully, others not.
So that's Loki and both Thors (Stand Up and Fight for OG Thor seems pretty spot on) covered, I'd have to see more about where Balder is at right now to get one for him...
