The thing is you should stop bringing "faction design" as a point, when it has been retconned through out the life of the COH cycle again and again. You bring the point that USF Riflemans in conjunction with their support weapons are so strong, that if they were able to get both, that either would had to be nerfed. Airborne gave USF the possibility since day 1 and it's not been picked for that reason.
USF use of 2 officers included using LT + Cpt and forgetting about Mayor. That's why call in tanks were nerfed as well.
I am not sure why in your opinion "faction design" is not a "point". Each faction is design to have different strengths and weakness, that does not mean that this should be set in stone and not change. But if one want to change the strengths or weakness of faction, one should redesign the faction for optimum results.
Airborne drop able weapons were very (and still are) expensive and took up 2 commander slots since day 1 exactly because they allowed access to support weapon regardless of officer choice.
I am glad that you agree that USF were designed to be played with two officers.
