I'm guessing there's a logical clause missing from your suggestion. However, if you read the
sticky you'll see that we are not currently interested in making t/m unbreakable as compared to same size attackers, and actually believe that them being breakable -- nearly double tappable -- is better for the game and makes wars more dynamic. We find the strategy of running ~15 t/ms and a smaller number of pure attackers to be unattractive, and that is largely driven by the defense heavy mentality.
If you feel like you are running too many T/Ms, then I would suggest you run fewer.
If your suggestion relates to making op success easier at lower relative TWPA, I'd be curious to see data about the successrates you see, and why you feel the success rates need to be higher.
