So, I like the terraforming feature and that we need to flatten terrain to build structures / walls, and that we can have villages on hills, etc. I don't have any issue with that.
I have to be honest, I don't mind the digging part of the terraforming, it's the constant need to interact, make dirt piles, move dirt piles one at a time, etc that drives me up the wall. I spend most of my time doing the following: Move dirt piles from quarry to drop off - > move dirt into inventory - > click and move to flag - > hit make level - > repeat.
The survey tool at first glance seemed great, and then later not so much. The fact that you can only make a rather small survey area, and you can't customize it with dig / drop off zones, makes it a very annoying tool to use. The fact that dirt piles only hold 80 units, and a wheel burrow can only move one stock pile is also painful when trying to terraform a large area. What's worse is that wheelbarrows can't drop off dirt in a survey flag.
So here's some ideas that I had.
*Increase dirt stock pile size to something more comfortable to work with, 500, 1000 units.
*Create stockpiles inside of wheelbarrow, e.g. if there's a few hundred pieces of dirt on the ground, I can right click the dirt with the wheelbarrow while holding shift and the wheelbarrow will pick up all of it.
*Let us 'make level' with a wheelbarrow.
*Give us some kind of larger vehicle to move soil with, perhaps have it pulled by an auroch / bull, think of it as a big soil container on wheels. Let it work like a wheelbarrow but hold quite a few piles of dirt.
*Make it so that we can have larger survey flags.
*Make it so that we can customize the flag area with our own 'dig' zones and 'drop off' zones, this means that you could have survey flags where one half of the flag is digging down, while the other side is dropping off to raise the terrain.
*Fix the 'cliff' issues when it comes to terraforming, often times I have to manually remove cliffs because the survey tool isn't good at it.
I'm sure there's other things that could be suggested and I hope others can chime in here. I'm just, sort of burned out on the terraforming part of HnH2, at first I loved the idea but it's taking up more time and effort than I can really spend and taking up most of my play time. I'd move to a flat grasslands if I could but I'm already very invested in where I am.
edit: more ideas
*Let us survey dig to stockpiles instead of only filling to inventory / dropping on ground.
*Let us make us make non rectangular surveys by having the ability to add further tiles to the survey.
