I've long wished for those to be replaced.
The quests & the rewards both need a total overhaul.
It indeeds needs a overhaul, but it's also important to know why it is what it is today.
When I started playing in 2015 I read an interesting intervieuw with the game developers that told us about quest cycling.
This ment you could cycle trough those quests and then pick the ones you liked. this included quest that allowed you to get for that time massive amountd of goods. I immediatly looked at it, and started to adjust my town to level 1 factories only as combined with quest it gave a massive amount of goods you could not aquire with regular production.
Quests at the same time could provide you with all the supplies you needed, this way you did not need workshops. this was very common and a large portion of the players had a very limited amount of workshops often just 1 or 2. all the other supplies came from questing.
So they tried to "fix" this.
One of the options they tried is to limit skipping a quest to once a day.
This broke pretty much every town on beta since every town relied for supplies on questing, legend claims that more than 50% of the players quit because of that change on beta.
So this change was reverted, players did not return, but it was never released to live.
Then they started to fix the "goods" quests they got several changes first a reduction in rewards which did not help, and later it changed to: "produce production Y 24h, collect X supplies, gain Z coins.
This was originally in for example chapter 2? produce T1 24h gain 1200 bonus goods since a building could never produce that much at that time in game, it was much easier to just build 3 level 1 factories instead of 1 level 15 factory and quest cycle the quests to get the reward once per day per level 1 factory.
So this solved the insane goods gain from these unlimited quests but it did not solve that all cities relied on these quest for there supplies.
They could not change this without breaking almost every single town in game.
The solution then became to no longer update the unlimited questline. as the game evolved people where slowly forced to build there cities properly with proper workshops. this way they solved the issue without having all players run away from the game.
This is why there are no new "improved" quests after the dwarven chapter.
An important takeaway of this story is that an overhaul need to take in account the lessons from the past.
It might let the "skip once per day" return, as it would not have the same backlash as it had back in the day.
Making interesting quests, with interesting rewards in an unlimited free for all format can't and should not exist, so if an overhaul would be made do not expect "unlimited" quest cyling anymore.
