I was just more concerned about losing 8 to 15 medals each time and trying to see if I could minimize that. And the only way to do this is only to get attacked by players that are ranked higher than yourself.
Assuming you have a solid defense, if you protect your TC, would you increase the chance of only losing to players who have more medals than you? This assumes higher level players have higher medal count, which is not always true of course. But if you have a max industrial army, would you be lurking below 2000 medals? I am currently at 2100 and I'm considering that option, so that I stop getting losses against lower medal ranked players, again assuming they have a weaker army than the ones who are ranked higher.
My defense is pretty bad (gunpowder level although I am in IA). It's not even a matter of gold investment, it's a matter of workers availability for me. I need to upgrade barracks, air strip, etc... for offense, I never get enough workers to upgrade defense. So currently, this is purely theoretical because I can't protect my TC efficiently even if I wanted to
