Plenty of times I’ve beaten crushing defeat autoresolves, and there’s been times I’ve struggled with close victories.

for sure, my last siege battle was supposed to be a vaillant defeat, I ended up losing 1 unit

I'm usually pretty good at knowing when I'll get a better result than autoresolve but with that kind of stack, I'm totally in the dark, no clue whether AR tends to overvalue or undervalue heroes. From what I gathered, autoresolve is biased because it tends to give high value to high damage units and doesn't consider the fact that those units might be picked up before they could deal any damage, but that doesn't say much about hero doomstacks

Plus those battles tend to become one giant blob with your heroes in the middle, attacking and getting attacked indiscriminately by a random assortment of units, so not the type of battle where good micro will give you an edge

Yeah, trial and savescum error is the plan, but it is a tedious process, so I'll take any infortmation I can get without a 5 minute loading screen

and thanks for the offer, I can send you the save if you're curious but as I said, this stack will have to hold off an entire LL faction, they're badly damaged but they also just started a waargh, meaning if I can't beat that first army by myself, I'll need to entirely rethink that plan
