3 Side battle with Breakthrough Style Suggestion

I am not sure if there’s already an existing suggestion like this. But anyway I’ll just drop it.
Kind of bored on the 2 Side battle on realistic battle tanks not Custom not Event!
Why not introduce a 3 Side battle tanks with Breakthrough style(inspired may be not fully) then the capturing flags who has the most points from the 3 sides will now the attack (the attacker has more tanks reserves) team and the 2 lost side will be defend their own base. Free to criticize or suggest better than this. Kind of bored, with the same old 2 side battle.

Theres a good reason 3 sided games are rare these days.

You mean the Breakthrough mode in Battlefield series?
