-The best thing you can do to counter the Perisan Douche is going fast feudal, and when i say “fast feudal” this mean (8:50, 9:15, 9:40), not higher that that and not lower, and if you are Mongols/Lithuanians, you can do it in less than that
-2nd step, move to archers/scouts to attack him in his base, if you just want to keep defend your TC and waist your time with repairing then actually you didn’t make anything good.
-build towers in your new locations after you losing your TC
*These steps are good too against Incas rush
But i agree with you that because they have 2X TC hp they should do something about it and a little longer time to build will be good
