Are you really playing as USF? How can one guy have 4 Jackson and 4 M8A1 with 100 pop limit?
Also, M8A1 is powerful because it's a 75 fuel AI only, 400 HP fragile vehicle.
Please show your playercard, so others can judge your opinion as inbalance or L2P issue.
Some days ago I had a 3vs3 versus 2 soviets and 1 US. After 60min bouth soivets owned a M8A1 and one Soviet a Jackson.
The US had 3-4 M8A1 and multible Jacksons and some rifemen, while I as Ost had full popcap with 1 Panther, 2 Grens, 2 PaKs, 2 Pios and one Arty. The game was long, I had enough ressources, but no Popcap. The only way at that point would be to let all my inf and paks die and build 4 Panthers to hunt the Jacksons, but versus the inf? Every infantry we killed incresed his potential to get even more tanks. And Ostheer without PaK40 or Pnzgrn+Schrecks is unplay-able.
What did the US do? Simple, he didn't attacked. He killed all inf and Paks with the M8A1 blobb, managed it to save ress and simply left his vehicles to get more Jacksons.
That mechanic is brocken. He is able to get an with ~130 - 150 popcap by that shit.
StuG E is shit in comparison. M8A1 is way too good, fast, good HP, self-repair and 2 shots most units. It is a Brummbär with more rage and more accuracy.
Only the fact that US can do that is enough to nerf or remove that Funktion.
Edit: for you maths:
- 1 M8A1 Pop of 6 -> decrew it and you only need 4 Pop.
- 1 Jackson Pop of 16 -> decrew it and you only need 4 Pop.
Now, let say you have 100 pop-cap, 2 Jacksons and one M8A1. Decrew them = now you only have Pop of 74 and build one extra Jackson, also decrew this tank and you can build an extra Jackson, also decrew this one and you can build again… an extra Jackson.
= Now, now you have 1 M8A1 and... 5 Jacksons. = That would be now an army with Pop of 148 and he could still make it higher. That is fair?
100-(12+12+2)=74 *an army with 2 left Jacksons and one left M8A1
74+16-12=78 *3 decrewed Jacksons + 1 decrewed M8A1
78+16-12=82 *4 decrewed Jacksons + 1 decrewed M8A1
82+16-12=86 *5 decrewed Jacksons + 1 decrewed M8A1
Now... he can still build 2 extra M8A1 by that way.
