"You" doesn't equal "most people". Sorry bud. Ask the balance team what criteria they use for balancing and they'll tell you 1v1, and good balance for 1v1 will carry over to balance for teamgames generally. Note: even though it doesn't look like it from my playercard, I play a lot of teamgames too but only with friends.
Also if they balanced to teamgames they'd have to buff USF and nerf both axis factions lol.
I know the balance team better than you. Maybe I get a strike, but most community members are simply salty trolls, not more, not less.
Maybe start modding and make something for the community instead?
Do you know what they are marking with the current patch? They make the fraction more similar. That is how to balance a multiplayer-game. That is balancing for larger modes, not 1vs1. See it, or stay blind.
Edit: This forum is twisting around, repeating everything over the last years. It becomes boring.
