Gold problem solution:
Max your first territory Outpost including 3/3 Weapons, never do the outpost or factory mission on your second and third territory, but max out the shelter militia 3/3 on both.
Make your Thread on your second and third territory to 0%.
Put some engineers or citizen in your group and skip days.
Your Gold problems should be gone, in less as 20-25 minutes you can buy all upgrades
too boorng to spend internet ressources or time in this game. you have a rock, than paper, iron gold and than only hellstones lvl 1 - x thousand not really a fun game, because you have to run this game weeks, to buy another 6% amage boost.
Better Example: you have to go afk for one week to spend your gold for another axe, which will allowed you to earn "Helstone" lvl 1987 faster as "Hellston" lvl 1986
There are some minor things which should be change for companions
1. You can grab more as 1 Monster in the mission (one should be the max).
2. When grabbed they are stronger and have more health as the non-grabbed (enemies).
3. They don´t give you gold for killing-blows.
4. When you grab enemies in the mission they don´t count for killing blows (for example: kill 23 monsters and you have grabbed 22, after this one is defeated your killing mission is over). Grabbed ones should count down the number.
