I wasn't asking for it, I was just theorizing. Mex upgrades are a good thing.
However, I do think there is too much scope in FA to make ecos infinite. I'm not a fan of mass fabs and infinite RAS SCUs. I think resources should be precious. Once you've got all your mexes to T3 and RAS on the com, that should be it, the way you get mass is to fight over wreckage fields after that. Why does there need to be a theoretical infinite amount of mass? It takes the strategy out of the game, because no matter how much you out maneuver your opponent, you will mostly lose if you are behind more than 10% in eco.
I've been playing a few team games recently and it's rediuculous, I see ecos of 600+ mass income just because people don't stop ecoing, so it just becomes an economy of scale instead of a strategy game where you move around units on the battle field and probe your enemy's weak points
