That’s what the statistics say:
These are Z-scores. Do you know how big the difference is between the highest Protoss (Zest/Hero) and the highest Terran/Zerg? 5.8 vs 2.5. We can convert these to IQ scores since they are a similar metric. 5.8 is equivalent to 187 IQ. 2.5 is roughly 138 IQ. So, the Protoss are still “geniuses” so to speak but they just aren’t on the same level as Maru/Dark/Innovation etc. Lmao. These players aren’t even remotely close to the same skill level. Protoss are like your garden variety genius. Serral is like the one in a trillion super genius that spawns once in a millennia.
Do you know how many Protoss have been blocked from a 1st place premier finish by Maru/Dark/Innovation/Serral? Probably like 15 or 20 of them over the years.
