As someone who mostly beat the game in hellichurl mode (conquered Mondstadt and Liyue, beat Lumine but not every boss), I resonate deeply with your suggestions. My main issues with the game are also how tedious it can get:Okay, I am done my first playthrough on hard, with 109-turn full conquest (around 20 turn was skipping around gathering resources just seeing what the colonisation was like), though I have not explored the abyss/maw all that much, and I hope that whatever drivel I write here might be useful:
- Tedious fights: Having to battle at the end of each day is a chore. It's never a challenge either. Just the same fight over and over again to defend against the enemy "resistance". Auto battle is the main way to curb tediousness. BUT auto battling seems to be heavily discouraged by its very nature. For one, you always lose some units despite the fact that you would never lose any in a controlled battle. Two, you can't capture girls in auto battle. Auto battle should be reworked if this issue is to be resolved.
- Tedious movement: I appreciate the fact that troop movement matters. This is a strategy game and having to plan where your units are going to be is a part of war strategy. But the map is big. And it's going to get bigger. Moving your units from Dadaupa Gorge to Natlan is going to take hours. Teleportation is nice but too costly to perform consistently. My suggestion would be to allow building outposts on the map. Outposts would be expensive and limited in number, but could enable one of two things: Teleportation to Dadaupa Gorge, or faster movement when passing through it. This would make reinforcing your position in front of strategic locations much less of a chore.
- Tedious unit management: You're going to starve if you don't manage your units properly. Version 1.12 brought wonderful ways to farm for food. However, inflating costs of feeding your army is still a thing. This means every now and then, you have to sacrifice some of your least valuable troops and girls. There are many QOL options such as auto fill or hold to fill, but doing it everyday is once again a chore. Automatically assigning certain types of troops or girls to be expended at the end of each day would be nice. For example, basic hilichurls could be automatically sacrificed, or villagers can all automatically be sent to the mines.
Balance is fine on hellichurl mode. I hope you don't decrease its difficulty. My units were, with some effort, able to take on fights at every stage of the game. In the late game, the top tier units could take down the strongest cities in a few waves of attacks.
Those are my main gripes. Overall, this is a fun game, and the porn isn't even why I'm here. I'm here because I love being able to conquer the world of Teyvat.
