Building workers is pretty much the foundation of any future play. It's the fuel that runs a player's engine in StarCraft. It's the mana of Magic: the Gathering, the production certs of Axis & Allies, the planetary resources of Twilight Imperium. I can't spend any time worrying about build orders or army composition counters or even the meta-game at large. Not yet, at least. As much as I love to tie my strategic and tactical gameplay into a greater philosophy or Sun-Tzu or something, there's a reason soldiers start at boot camp and aren't just shipped into combat. Eren in Attack on Titan doesn't strap on the Three-Dimensional Maneuver Gear and get right to titan-slaying without some serious training. That's the way it has to be for me, as well.
So I've looked up some notes on the changes to the game, watched some videos by Filter, and started drilling against the AI. Not to practice tactics, not to ensure wins, not to nail down build orders. I'm just making workers and basic units, focusing on the workers. So far, Terran and Protoss are going fine. Zerg, I'm struggling with. But I'll get there. And when I do, at that point I'll jump on the ladder and start fighting live opponents. Though 'fighting' may be a bit of a stretch, as all I'm likely to do is bunch up all of my basic dudes and lob them at the enemy with no real tactics involved.
Then again, I don't think many people at Bronze level will know what to do when 50 Marines or 30 Zealots or 40 Roaches come knocking at their door en masse 10 minutes into a game. I guess we'll see once I have my benchmarks nailed down.
Those benchmarks are:
Terran
10 minutes: 52 SCVs
Natural @ 3:20
Protoss
10 minutes: 56 probes, 18 zealots, 8 gateways
12:30 - 72 probes, 3 bases, 8 gateways
Zerg
Drones
6 minutes: 30-35 drones
8 minutes: 50-55 drones
Queens
Less than 10 energy combined @ 10 minutes
6 minute quad gas
7 minute Roach Warren
7 minute double Evo Chamber
