Look up Literal Barracks Rush on the tl forums
This is a low level upgrade at the engineering bay for 150 minerals and 150 gas. It will help the terran become more balanced.
And let the Barracks squish units when they land. It will be balanced because this can harm both enemy and friendly units!
And if they are on top of buildings, they will bounce up and take some damage and you can keep ramming them until that nexus is flat.
Look, Terran needs more cheese options, what better way to win against a zerg than to maul over their overlords with rapidly moving barracks? Supply block them? And then destroy their entire mineral line!
And imagine the look on Tassadard’s face as a swarm of Command Centers smash though an entire Carrier fleet taking down the Mothership.
