Someone with an Amnesty International vest buzzed my unit then threated to fight me while taking off his vest when I told him "Not interested and get off my porch" so if you get your doorbell rung by these 30% cut of charitable donations mofos and one of them is named Alex, make sure you know your karate
I had two matches in a row with the same guy, we actually failed the first mission (temple of the past) because the guy's Dehaka army of ravasaurs and like 4 hydras kept dying but I was never really watching on screen since I figured we'd just be facerolling everything and was focused on my macro, spawncamping, the usual chill stuff. Enemy comp was like protoss scout/zealot/whatever.
So I queue again and it's the same guy and I just mention that maybe he should have mixed in some more hydras to his army and he was like "yeah, weird how they kept targeting my side". Since it was the Void Thrashing mission we were on the same side of the map the whole time and as I watched his army movement I realized he was just right clicking everywhere. I told him to use attack-move instead, then watched him keep right clicking on the OTHER side of the map and I mentioned a-move. No response either time.
After the 2nd game ends in a victory, the guy asks in chat what I meant by attack-move/a-move. I told him exactly how to do it and why it's better than right click, and he was like oh I never knew, thank you very much.
So just a little story about not being toxic, trying to help other players improve with the basics, and that ooh man yeah there are some players with a LOT of time in this game who don't know the basics but ya know everyone was a noob sometime. You can get angry or you can help someone out and make the player pool better.
