ok how to counter the fast engis upgrade with double flames?
In a 1v1 context, you don't. There is absolutely no counter for the ingenery spam. It's quite literally unbeatable if the player knows what they are doing and if you don't believe me go watch the replay of someone beating 2 Wehrmacht by himself with it 1v2. In theory, it should be unbeatable on any map, with any number of players, but it gets harder to do in 3v3's and 4v4's. I have played game after game and never even broken a sweat and its beaten just about every strat you can think of. If you can't tell that is absurd and game breaking after one glance you need your eyes checked.
I understand that you want to give it time to let it all sink in and let people develop more advanced counters, but really it's all ready
painfully obvious that the Soviets are super OP.
