The Prestige system isn’t supposed to restrict building, but rather reward the efforts. If the system does pervert players actions then we’ve not got the right solution. I agree with @Spoygg that the value ranges are too great at the moment. The ranges should be much flatter.
But the algorithm doesn’t attempt to do this.
The algorithm is setup to encourage some block variation, some usage of chiseling, some colour variation, etc. Just some. It’s not absolute.
The prestige system attempts to give Builds a level in the same way player Characters have a level. It’s up to a player how they level, likewise it’s up to the builder how they design their build. But the game doesn’t say one character build is better than another, likewise for similar level builds.
