After rushing and finishing the Lantern Rite event (plus the prerequisite quests I hadn't done yet) before time runs out, I finally started the Sumeru archon quest and I must say it's enjoyable to have something to do that is not just spending resin and grinding for materials/artifacts. It's cool to explore this new area, hunting treasures and dendroculi, solving puzzles, and following the story (even though it's too talkative as always).
And the good thing is, because we're already deep into v3, hopefully I won't have to wait too long for Fontaine after I completed Sumeru.
Speaking of Fontaine, I wonder if 4.0 will be as hype as Sumeru. Sumeru was special as it added to the game a brand new element and whole new set of elemental reactions. It deeply changed the meta and the characters' synergy overall. Obviously Fontaine can't do the same. And Hydro is already one of the strongest elements (if not the strongest one), so there's no additional relevance to look forward to; unlike Geo which we already have explored the nation of its archon but it doesn't feel like it at all.
Really I think Mihoyo should do something with Geo and Physical DMG in the future; maybe tie them both in some way since the two of them feel neglected, so why not solve their issues simultaneously?
Cryo could also benefit from this rework since it's already related to Physical DMG through superconduct, and its other elemental reactions took a step back after dendro's addition.
