It stopped because i left. I got Carriers as a last resort (Knowing full-well that they'd be pooned) and was like
'OMG GG COMPS I GOT CARRIERS OLOL', until they were targeted so heavily by anti-air
I eventually couldn't do a thing, i ran out of minerals and i was getting frustrated at the pissy attacks that the comps keep making (One Goliath here, a Zealot there, etc etc).
