ATOSTIC excessed an insane amount of metal. :/
There's no excuse for excessing 11K metal by 24 mins. I know that microing that army/Widow is very important and takes up all your attention, but surely you can put something on repeat build? Just repeat build Dantes if you have no other ideas.
Also, rebuild quickly when you're destroyed! After that Ultimatum came through and wrecked everything there was still the advanced geo, those mexes and a whole bunch of reclaim.

If 4hundred had put a missile silo next to his corner porc he could have wiped out everything important for both his enemies 1/3rd the way through the game (after he rebuilt).

Seeing 4hundred lose 30K of metal to a measely 8K of attack force and missiles because he doesn't bother to build a few smaller backup defenses (newton+faraday+gauss+stardust costs 1070 metal and would stop Chesti's force in its tracks, saving 20K eco) or a modest army. :/

That resign came way too early. 4hundred could still have won given how ATOSTIC wasn't even rebuilding.
