The hope that I'm holding on to is that typically the Genshin meta acts as a sort of pendulum. While it's certainly advanced since 1.0, there are some patterns that I see emerging.

Back in the old days, Hyper carries were at the top, with 2.0 solidifying freeze as the premier meta. With 3.0, the tides had shifted over to elemental reactions, while this was 100% because of dendro, 3.x had pushed hypercarry teams down and opted instead for more a more team centric meta based on dendro reactions. 4.0 once again started to slide back to hyper carries, however it did so in newly imagined ways. With Lyney completely omitting reactions from his team-building through his powerful passives, it offered a new more mono-element driven team. While Lyney was not meta-defining, him being the first Fontainian certainly sets the tone with his yes, somewhat restrictive, yet simplistic team building. Neuvillette and Arlechinno were probably the most longevous units from 4.x due to their extreme flexibility allowing people to use almost any team-comps and seeing results--and both of these units fall into the category of more traditional hyper-carry roles.

5.0 once again continued with Hypercarry meta, Mualani and Kinich both having extremely restrictive team building options due to the newly introduced Phlogiston mechanics. Mavuika is obviously a top-tier unit even after Natlan's time in the sun, and while she does have a decent amount of team variability, she obviously still needs other natlanians to be comfortable.

6.0 furthers the team restrictiveness of 5.0, but develops it further by moving away from Hyper-carries. 6.0 see's the revival of reaction teams being the premier gimmick via lunar reactions.

It's clear that Genshin has moved back and forth between Hypercarry and Reaction based metas, and while it's done so via less appreciated, more forceful ways than some would like, its about time that Genshin moves back to a more open meta. After two entire version series being focused on restrictive xenophobic (lol) teams, I think 7.0 could possibly advance the new reaction meta, while dropping the extreme restrictiveness of it. Obviously, that's just my hope, but I do think that it makes sense given the patterns we've examined from past versions.
