Another problem is that this asymmetric design is inherently impossible to balance. The USF can win early in 1v1, but they get their asses kicked everywhere else
This is because it seems like the CoH3 game designers spent all their ressources on 1v1 and didn't spend one day thinking about teamgames. The whole USF faction is a perfect example for this as you realized, the entire unit roster clearly was designed by someone who never played a single CoH teamgame match in his life. The DLC Ranger Battlegroup 10 months after release was merely a slapdash fix for this problem.
For some insane reason, they were under the impression that 1v1 is the most important mode in CoH when in reality 90+% of the playerbase doesn't give a single shit about it
