Sigh, again this discussion.
Someone already said it and stated perfectly.
To "fix" teamgames, specially 3v3+, we need to adjust resource gaining (specially Opel + Caches) so that the game becomes less "spammy". But that can be the whole reason someone plays those modes. So in order to balance it, you have to take out one of the reasons someone may have to play it.
If it benefits one side over the other to spam, then YES, it should be fixed if 3v3 and 4v4 are popular modes of play.
You WANT the game to be fair in the popular modes if only to make sure the most people play it. More players equals more $ for Relic. More $ for Relic is good for the franchise and the players in general.
vCOH solved this for the most part on some of the most popular maps. High resource points were absent as were medium fuel points. This made teching and spamming more difficult and team work, map knowledge and map control more important. If the game lasted long enough that was very friendly to Wehr. If it lasted longer than that it could actually again tilt towards Allies as the Allied units vetted. (For this it is important that earned vet is, at the highest levels, superior to bought vet).
Red Ball and Montargis were the most competitive maps because you had to outplay the other team. And control of a predominance of fuel or munitions could change during the game several times.
And over time lots of things that were "cheesy" in early patches were changed. It was once possible to get unlimited armor replacement from Allied War Machine. That was nerfed down to 2 replacements.
