I enjoy playing Stetmann and he’s probably one of my favorites commanders for several reasons: Super Gary, Stetzone, his units,… they check all of my personal marks but I’m not here for that.
What I noticed from playing with randoms is people generally EXPECT a Stetmann to spread Stetzone to their base, and while this is situational beneficial, Blue Stetzone does not work as straight forward as what most people seems to perceive it to be.
An Explanation on mining efficiency:
There was a Reddit post recently that touched on a similar topic: <https://www.reddit.com/r/starcraft2coop/comments/bu7z39/a_little_tidbit_about_2121_worker_saturation/
The main take away from that reddit post is: The first worker is +100%, the second worker is another +100% since it can smoothly switch with the first worker, but the third worker only adds about +50% due to the workers’ having to wait on each other. So a 3rd worker only add half of mining value to a mineral patch compared to the other two, therefore any 3rd worker should be sent to far mineral patches while maintaining 2 workers on each close mineral patches to get the most value out of your workers.
How does Stetzone affect mineral line?
Stetzone increase worker movement speed only, it does not make a worker harvest faster, it does not increase the income limit of a saturated base, it simply makes a worker move and return from a mineral patch faster. Stetmann himself benefits most from this while his ally only get 50% benefit.
What this boils down to is a mineral patch and a geyser only needs 2 workers to reach max or very close to max saturation while under the effect of Blue Stetzone, meaning if you have 14/21 at main mineral patch, it is mining as much as 19/21; a 2/3 gas is as much as 3/3 gas. The number 14 is very important for this topic. To make the best use of Blue Stetzone, a player can stay 14 workers on mineral line and 2 workers per gas geyser for the first few minutes of the game (ideally before 4:00 mark, while Gary is offline) and have the same mining rate as a fully saturated main base while teching up and expanding.
How does Blue Stetzone affect commanders?
More than half of commanders will not gain much, if any, value out of Blue Stetzone because the window of benefit is long gone by the time it takes for Stetllites to spread to their main. The main reason is that when commander have exceeded 14 workers, Blue Stetzone becomes less and less useful.
How to determine if Stetzone is actually useful for a commander?
Someone who knows about Build Orders better than me said this:
the commanders that could benefit from stet speed zones early (assuming skilled players, etc) are the mineral limited fast expand commanders. As the biggest benefit is using the mineral boost to get a faster CC and faster expand which itself gives an additional boost."
In my own understanding, if a commander has any of the following tool, they will not need Blue Stetzone as much as commanders that do not have said tools, distance is also an important factor to consider:
-
Autogas: saves 6 workers, meaning the player will pass 14 workers within the first minute while you’re spreading Stetllites to their base.
-
Fast worker production: Chrono Boost, Zagara Twin Drone allow reaching saturation much earlier than usual, making Blue Stetzone useless within the first minute.
-
Distance between 2 player bases: Depending on map, it would take between 3 or 6 Stetllites to reach your ally base, the more Stetllites it takes to reach your ally, the longer it takes, the less benefit they will gain.
With these factors in play, here’s a category of commanders based on if the effort to spread Stetzone to them is worth it:
Yes:
-
Kerrigan: Slow larva production rate + losing worker to make building means her worker count will stay low long enough to gain benefit.
-
HnH: Their expand method requires mineral, relatively slow worker production.
-
Swann: same as HnH but he has slightly faster worker production thanks to the last revamp.
-
Tychus: Mineral is his main bottleneck so Stetzone is a welcome boost
-
Raynor: MULEs mine independently from workers so Raynor uniquely gain a bit more income from faster MULEs.
Maybe:
-
Stukov: He is an edge case, botherline Yes category but I put him here solely because his Broodling expand method doesnt consume mineral.
-
Artanis, Karax, Alarak, Fenix: All have Chrono boosting their worker production so distance will be the deciding factor if spreading Blue Stetzone is worth it or not. It gets tricky with Karax and Alarak as both can open their expo rock very early, opening more mineral patches to mine from that could use Stetzone at expo.
-
Abathur and Dehaka: These two are a special case, technically they will gain from Blue Stetzone but their unique Hero/Monstrosity gameplay makes them care very little about their economy. Why bother with extra minerals when you could roll over the map with unstoppable Hero monsters.
No:
- Nova, Vorazun, Zeratul, Zagara: Not much explanation here, these commanders saturated extremely quick so spreading Stetzone to them is useless.
So what should you do if your ally does not benefit from Blue Stetzone?
Definitely not spreading Stetzone to their base, that would be like giving grocery money to your rich friend: they dont need it. Spread those Stettlites out to gain vision, a Karax would love to have permanent vision on the map, Alarak can Overcharge Stettliles to kill Amon force with no risk,… There are so many commanders that can make use of the vision Stetllites gives it would take a guide to list them all. Dont stay on Blue Stetzone all game when all of your bases are saturated, it does not give any eco boost in that case. Use Super Gary more aggressively, that guy is capable of solo maps with the help of Stellite Overcharges and a bit of kiting. Stetmann is much more than just a guy that gives you a Blue Stetzone that you may or maynot benefit from.
