Is it safe to assume an opponent still on one base in TvT is going Banshee? I just played a match where I scouted and noticed even at 10 minutes he hadn't taken his natural. I assumed it was a starport play and built a couple precautionary missile turrets - I was right and counter pushed after his harrass failed and ended the game. Is it safe to assume if the opponent doesn't 1 Rax FE that Banshees will be next?
