The fun thing is that alphastar did have influence on the starcraft scene. Overbuilding drones used to be taboo, now everybody does it. And even individually microing stalkers ... now it's quite normal for players to go out with 2-3 stalkers and indeed individually control them. These are good tactically, even when you're not an AI.
I'm very out of loop on SC 2 meta, I've played only in the past and up to Gold as Protoss; why is overbuilding drones considered to be a good thing now? Is it to reduce the economic setback in case you get harassed?
More reasons than just that. Overbuild drones while expanding (or even before) and then transfer to have a new base up and fully droned in construction time + 10s. You overbuild because you're going to lose 1-2 drones to any capable attack minimum. You can risk more on the defense when overbuilt. You have bigger chances of being able to expand during a base trade, ...
