I mean 1/1/1 is a solid build until you get 40 speedlings and 20 banelings saying hi and then it doesn't really matter much. I mean, you see what 4 banelings for a supply depot? So 12/16 for a rax or fact?
They could concievably bust your fact or rax down before your starport finishes and unless you have like 12 hellions the ammount of speedlings they can make will have you fucked.
absolutely, but the whole point of that original scout was to modify the build for what you see. If you see the speedlings off a 6pool or banelings, then you wouldnt proceed with the starport. The rax scv is a bit late, especially since it will be closer to 14 than 11 or 12 since the refinery is probably off of 12 or 13.
But 1 or 2 marines, protecting a 2sup1rax wall can stop early lings with an scv repairing. generally the fac comes soon enough given the right map size. But even still, i went for a raxfac wall and got raped because he hid his first 6pool lings so my scout wouldnt see. Got me as my first marine was coming out. Of course the wall wasnt finished...and i lost. But it was just a tricky situation.
