Game was never designed to 12 worker start! Each race is balanced differently and was designed to work on 6 worker start. However you can skip worker start at least to 9, if you do that right, but Blizzard can’t do basic math. Let me show you why:
Supplies provided per base:
In HOTS:
- Terran had 11 supply
- Protoss had 10
- Zerg had 10
In LOTV:
- Terran has 15
- Protoss has 15
- Zerg has 6
So in LOTV Protoss gets one more supply, than he had in HOTS! That’s already huge deal! Also did you know, that in HOTS, Protoss had to pause probe production to get pylon at 9 supply ?
Terran had 11 supply, because he is building with his worker!
Also Blizzard forget about one important thing. If you started with 6 workers, at the time you get to 12: workers would be already stacked! But in LOTV: workers start unstacked and than follow different routines, than they would, when starting at 6. Also that timing when protoss had to go build pylon at 9/10 and than go back doesn’t exist! Which pauses probe production and delay mining slightly! So 12 worker start if completely different game!!!
Also second thing: you would have certain amount of minerals at 12 workers, each race different amount! So to skip 6 worker, while not breaking the game: you would have to start also with minerals in bank!
Reason why more than 9 worker start is bad idea. Because you don’t start with production facilities like rax and supply depot. But in case of 6 worker start, rax would already started at 11 supply. Making 1st mule hit sooner, which means 2nd, 3rd, 4th mule hits also sooner! But in LOTV you start your rax at 15/16 supply! Meaning Protoss would has more probes, than he would have in HOTS, when first mule hits! Also in LOTV you start with one free chrono boost per nexus, which gives you perhaphs small early game advantage. Both LOTV and HOTS chrono boosts are same in terms of efficiency, at least until late game: because with LOTV chrono boost you get one for free. So if you wanted 12 worker start, you would have to start with depot and barracks.
Which also removes 2 proxy rax, or reapers, if you started with production facility building. SO MORE THAN 8-9 worker start is bad idea!!!
You can watch any pro game and compare HOTS TvP, with LOTV TvP and you can see difference! And yes some games protoss would have natural even massively later, in favor of MSC, but on medium to large sized maps, nexus hits at the same time!
So there you have it: mule hits much later in LOTV in comparison how many probes would Protoss have and when he gets his 2nd nexus., than in HOTS and this causes Terran is behind in economy significantly!
Also mule was nerfed from 240-270 to 225 only and also since less minerals per patches, (which was one of worst decisions in my opinion), you can break your mineral line:
- if you mule wrong patch
- or multiple times same patch
Also supply depot building time was nerfed from 18 to 21!
Also faster economy favors Zerg, because he can spend his bank from larvae, but other races have to establish production facilities first. In LOTV there is larger defenders advantage, which favors Zerg!
