Only speaking about 1v1 and 2v2:
Soviets have the strongest late game with very strong doctrines to fill the gap. the main problems are their pop cap, which is insanly efficient and the zis gun that can used as indirect when needed. Most other armies cant afford indirect in 1v1 as manpower and popcap are very tight.
Once the soviet army is set up with double zis, mines, t70, sandbags, 7man cons, mediums/heavy etc, it is very tough to almost impossible to break their line.
The problem is the synergy of their combined arms is simply stronger than any other army, so there isnt an obvious nerf that would fix this issue.
as a >1000 2v2 player, i totally agree and being saying so.
dont forget cheap su85 + easy vet + insane vet bonus + call in any heavy armor
For a start 7 men cons + sandbag was always a weird decision. Why is there plan to nerf Ost VSL before 7 man cons?
zis barrage range should reduce to 50.
ISU152 rear armor should reduce to 100.
reduce hang time of mortar sight flare
