Taking idea Hammer-Anvil British and the Okw icons when it was released something could be done to avoid OKW from being linear and getting free upgrades when choosing a branch. The units/skills can be others, no specifically these.
The WEHR/OST bunker is built at the same time for all squads. Imo should have more time to squad not pioneers, something like Riflemen with mines/defensive position.
The beloved Brummbar has a high speed, to be a tank dedicated to hit the ground. Compared with other Soviet tanks or other non-EFA factions. Although it can be hunted by medium tanks, it is still the fastest tank in its role with a high armor front and back. I suggest down a few decimals their speed_max. This will lower the reliance of putting brummnbar in first line.
We're aware that T34/85 E8 might be in a bad light atm. However, we first want to figure out the right spot for the OST Panther before we start considering what advanced mediums should bring to the table.
When the Panther hulls down, you will probably have to use AT guns or artillery or infantry pushes to make it move.
Although we are at an inflection point with those tanks. Any change would be good, but maybe affect the Pershing who is an improved panther. Long time Relic introduced some T34/85 doctrinal (Red banner) were better than the present /85 and come retired, are within the files of the game and as for the Americans I believe that there are also some sherman with more caliber.
