I was playing a TvT quickmatch and my enemy was turtling so I took the liberty of expanding around and keeping a scout to see what and when would come. He was going for heavy air building battlecruisers and vikings, so I built myself an army of vikings and some ravens for the defense drones. He attacks with ~ 6-7 BCs and ~10-12 vikings and I go to meet his army with my army of ~25 vikings and 3 ravens. I pressed "D" to put the drone down and focus fire on the cruisers while the vikings get their missiles intercepted. While giving the waypoint orders to chain attack battles I realise that my waypoints did not connect. Oh, snap! I had vikings selected when I pressed "D". Pityful, pityful loss, lolz
Yeah, lol! I was like "DOH!, /facepalm". Funny thing is that he barely survived with 3 heavily injured BCs but having them shooting at my production buildings didn't let me gather a little army to come back in the game as every unit that was produced died before doing any damage... Oh well, a lesson to learn, lolz
