Terran and Protoss infrastructure are so expensive,
For example Terran loses between 1200/0 and 1650/0 just for building barrack in a game, they loses between 300/200 and 450/300 just for building factory and they loses between 150 / 100 and 450/300 just for making Spatioport. (On 3 or 4 bases)
You can add to that cost from reactor 50/50 x6/7 = (300/300 or 350/350 and cost from tech lab 50/25 x4/5 = 200/100 or 250/125.
And you can add to this 400 x 4 = 1600/0 for the price of Command Centers.
For a total of 4750/1075.
In others hands you can see how much cost Zerg infrastructure on 4 bases :
4 hatchery = 300 x 4 = 1200/0 + cost of 4 drone = 1400/0
We can add to that spawning pool = 200/0 + cost of 1 drone = 250/0
Then add Baneling Nest = 100/50 + cost of 1 drone = 150/50
Then add Lair = 150/100
Then add Hydralisk Den = 100/100 + cost of 1 drone = 150/100
For a total of 2100/250.
So in conclusion : Terran are force to investing 4750/1075 ressources into building on 4 bases when Zerg need only to investing 2100/250 ressources in infrastructure on 4 bases.
The broken thing is your maths, you forgot to add the drone cost to the total building cost, a pool is not 200, is 200+ a drone that cost 50, so a pool cost 250, a hatch cost 350…
But that’s only one part, the most important part is how the eco on the game works and interaction between units, Z units are less efficient, you will get 20 lings and many of them won’t deal any damage. And also you must build queens to having a decent production, queens should be treated as buildings and not like actual fighting units, yes, they are really really good at defending, but they are necessary for the macro just as Orbital commands or PF are, so in the end, a proper Z production requires 300+50+150=500 per hatch.
Afaik a Zerg building consumes a Drone, which costs 50 Minerals, that cannot be used for mining. So I think you can add 50 Minerals to each building you mentioned.
4x Hathery -> +200
Pool +50
Banelin Nest +50
Hydralisk Den +50 — Do Queens count as buildings for Larvae? 6x Queens ==900 Minerals
A Command Center adds 10 Supply - 1.25 Overloards -> 4 CC == 5 Overloards == 500 Minerals for the Zerg.
I am not sure if your calculation is well thought out.
Assimetrical balance, trust me, building cost are not a part of the ‘‘problem’’, yes, T invest more, but has that thing that makes them mine more, around 225 minerals per click, that’s more than 1 free building past the first mule, you get two mules?, now you will have 450 extra minerals.
And what I said, T army efficiency is usually higher, T troops survive more, they deal more damage, Z units die a lot, so they must be replaced so in the end, the building costs are basically nothing compared to the army efficiency.
Oh, and another thing, having more buildings is not that bad, you can have walls, and create choke points, Z can’t do that unless you want to have a wall of useless evochambers, and during basetrades more buildings are a good thing,specially if most of your buildings can fly.
I think Zerg hatchs do cost less minerals than a CC, even accounting for the drone (300 +50= 350M) because the resources the drone would’ve mined during its life are also lost.
Now, that’s for the hatch. However Z not having to invest into an amount of production structures proportional to the related tech is definitely an advantage in early and lategame. The cost to produce let’s say roachs on two hatcheriess, which could be produced by packs of 12 (24 supplies) , doesn’t compares with the gates of a protoss, and even less with raxs requiring addons.
That’s balanced in early TvZ by the cost efficiency of the wall-in, of the bunker, and of the terrans units. And that’s might be part of why protoss do have more issues in PvZ, and why the devs went for a shield battery mechanic.
On a side note the protoss being able to bypass walls more easily than Z, while not having the addons liability in terms of production timing/rate, might on the contrary be part of the reasons why terrans don’t have the same efficiency in TvZ than in TvP.
And what about the supply lost and the extra time you need to refill that drone? In addition of the larva time that you are not spending in any other thing? And what about the time that drone is not mining because it’s being spawned in hatchery?
Hatchery should cost 400 mine and drone should not die. And that would be a Zerg buff
It’s a bit false, because in contrary of Terran or Protoss, Zerg can build as many worker they want. If you sature your bases fast you don’t lose ressources from drone that you used to build structure.
And why don’t speak about SCV Terran don’t mining when they create CC or supply depot or Barrack ?
If I’m a bit false then it means that I’m a bit right as well.
As for Zergs’ drones production rate, that’s more be linked with the larvae production rate (which could be tuned for balanced purposes, if needed), than to the building cost itself, as the speed the drones are produced doesn’t change their cost nor their individual mining.
Offsetting that is what mules are for.
The real question would be the duration for which the CCs are unable to produce workers while transforming into OCs, and for which the buildings are unable to produce unit while producing addons, if you ask me. That, that could be discussed.
