To start I do feel that any RTS, CoH 2 included, should be balanced for is made game mode, which is normally 1v1s.
why so categorically ?
I only can repeat: have you noticed that topics concerning balance problems in 3 vs 3 , 4 vs 4 modes have being emerging increasingly ?
What does it mean ?
At lager scale it means that people nowadays are more interested in team modes rather than in 1 vs 1 in all games, and COH2 is not an exception.
There are measures to settle properly balance in team games not abusing 1 vs 1 modes! It is only question of wish and hard work.
