Have you recently seen our monthly donation goal? /fix is one of the ONLY commands worth donating for, much less coughing up 80USD and you're worried about what it might do to the arbitrary prices of diamonds
Personally, I think /fix should be left as is. It is stupid that minecraft put a limit to the amount of times you can repair a pic. But with the Mending enchantment in 1.9, all the controversy over /fix should be gone.
I see the economic reason for doing this, but I also see a reason to not do this with involves actual money.
Pros:
The god tools that people love to sell will actually become slightly valuable again
Diamonds (And to an extent iron) will have more value in the market
Cons:
Extreme rioting and disagreement will occur due to elites+ who like to have /fix as it is
God Tools that people love to sell may become a bit pricey for people with less money
A perk that some people paid for will not be in the rank anymore, giving less incentive to donate for the rank.
Overall bad trust from server->player. Ex: If I donate for /feed in premium, what are the odds that it could be removed because it doesn't let food have value?
I'm at a -1 but both sides do have viable arguments.
