I absolutely love how, in the middle of rattling off 300 words a second, your brain compulsively finishes the erectile dysfunction analogy... I replayed that a few times...
Raven versus mutas or corrupters isn't great, because they can jump on top and snipe it. And it delays medivac production by a lot, so making a second one is really nasty, even if losing the versus got you 5 or 6 anti armoured mutas or corrupters. But also, pig was panicing bassically from minute 1, and making a raven requires calm thoughts.
hell of a lot of starport time, you have to lift off the starport, build a tech lab, then actually build the Raven, lift it again, put it back on the reactor. It also costs 200 gas whereas scans only cost minerals.and could just be sniped by corruptors.
