Before even getting into why changing t3 mexes is necessary (it isn’t) it should be asked whether it’s even good (it also isn’t).
Games have certain fundamental pillars which everything else is built upon. When you change something as base as mex values, you have essentially reached the point of full circle for FAF as it is one of the few things that has never had an adjustment.
Why has it not had an adjustment? Because it’s an extremely important frame of reference which allows every other relativistic change to be put into the same optics. You change it, you change how everything goes and looks. And a lot of that will just shift the goalposts back to the disaster of old balances, maybe even back to the shitfest of GPG.
No, you want more aggression in the game change unit costs, not the eco buildings.
Reclaim stuff sure whatever, it doesn’t change any real truth surrounding the game. It just adjusts internal calculations for what is/isn’t worthwhile which hardly destroys the structural framework of the game.
