like 2 rax fe, 1 rax fe, and mech builds. I always can't get out many Vikings to counter COllos. What do you dO when they do nexus first builds and make multiple bases by like 12 mins. Evn if I try to attack before cOllos comes out, the force fields always kill me. I tried getting out ghost early, but I always end up with less army. TL;dr: What do you do when toss expands like crazy in mid game and how do you get Vikings fast enough?
