The only thing I found wrong with 6.0 was just how obviously lopped sided the handling of the story was when it came to the Final Days and everything revolving around that and the more slice of life and comical parts of the story. Too much focus on the latter, when there should have been more focus on the former. Shadowbringers had this down perfectly.
I also liked the way Pandemonium has been handled so far. Never expected the nut case that was Lahabrea in the present timeline to be previously this kind of person, not to mention him being a family man on top of that. xD
I also hope Athena comes back in some shape or form, too. Its totally possible since obviously Lahabrea completed her work in the end. I don't think the Lahabrea that was killed by King Thordan was the same one we met in Pandemonium either. Possibly a repurposed Hesphestios with altered memories to make him a complete copy of Lahabrea, so the other Ascians wouldn't catch on to what he was up to. I suspect the real Lahabrea is responsible for Pandemonium's reappearance in the present and that he's been continuing all of Athena's unfinished business while preparing to fully revive her in there.
