So you mean, that for each tank, you can build round about 6 - 7 engines instead!? ... and bring them to your breakdowned tanks?? Either I don't understand you, or it just make no sence ... :blink: Cause you can't build 3 tanks and than make 20 engines out of it to repair the others!
But I agree, that an extra pool for damaged equipment will be too much micromanagement ..
Simply reducing production numbers to keep all units in 100% working condition is a huge problem. Tanks literally would break down after 100 to 400 miles depending on the tank (we can assume that this would be affected by reliability).
Now let's say we launch barbarossa, Tanks are travelling several hundred miles ( 4 provinces ) and your solution is to reduce production to keep them all at 100%? That means that there will never be supply problems, all your units will always be 100% strength unless the units are actually destroyed in battle.
What should happen:
Unit has 400 tanks with 0 reliability points.
1st province you lose 50 in battle, and 50 break down. 50 move to unusable pool.
2nd province you now have 300 available, you lose 20 in battle, but since your attacking without stopping the losses to breakdowns increase to 80.
3rd province you now have 200 available, but you have outrun the enemy. You lose 140 tanks to breakdown.
4th province you now have 60 available, you army should be forced to stop unless you want to have no equipment left.
If you want to simulate repairing those broken tanks by simply abtracting it into the production line where 3 produced tanks repairs 20 broken tanks, that's fine, but being able to keep your entire division equipment at 100% and take away units from production is a huge problem and takes away the point of even having reliability as an upgrade and makes infrastructure even less important (something HOI3 faced). It also unbalances the game by allowing attacks to continually keep advancing without any stop (something that really affects the Eastern Front and China theater tremendously)
I don't see how this increases micromanagement at all (except maybe adding a button to equipment pool view to use equipment to repair units).
