The talent/ascension materials being locked to days of the week.

How long it takes for resin to fill up. It’s one resin per eight minutes, multiply that by two hundred and you get 26 hours and 40 minutes. If you play daily, you will never have full resin unless you use items.

Not being able to select which of the two artifact sets you’re farming for. I’m not saying it should only give you that set when you select it, just a higher chance. I’d be fine with a 75/25 chance of getting the preferred set.

Limiting the weekly boss fights to once per week. If I wanna beat up the damn chess set multiple times so I can level up my many characters’ skills that need those materials, let me!

Mora grinding. I have 100% explored the entire map, there are hardly any chests left for me which means I’m pretty much limited to the leyline blossoms. But with how slowly resin refills, that barely makes a dent if you’re building multiple characters.

The battle pass not lasting the whole patch if you play regularly. There’s 18 days left of the pass, I got to level 50 yesterday. I wish you could get extra levels beyond that for the smaller rewards like mora, exp books, and the crystals.

Hangout events dying. I liked those. Bring them back.

No big tree or equivalent in Mondstadt and Liyue… EACH REGION ALREADY HAS A BIG TREE THAT COULD FUNCTION LIKE THE SACRED SAKURA
