One thing bothered me is that Miners has 3 pop, like literally same pop cost as starter units (archi, sword, etc) while they maybe the backbone of the economics, 3 is a bit too much fielding lesser units amassed. I suggested these reduced cap cost coz even in coop u only have 75 max pop.
For the balances, I believe;
Miners - 2 pop, Enslaved Miners - 2 pop (slight has more movement speed compared to order counterpart), -30base HP (since they have regeneration)
Light Units - 3 pop (doesnt matter what type, except for expendable frontlines)
Light Units - 2 pop (crawlers, dead, swordwrath,miners, e.miners, sicklewrath)
Light Units - 1 pop (literally that bomber chaos unit)
General unit - from 9 to 8
Buff base hp of dead from 60 to 80 seeing how squishy they are, and increasing cost from 50 to 75 like sicklewrath variant
Buff base healing of the hero meric unit from 20 to 30 OR 20(+10 to heavies)
