I would like to suggest making items unbreakable for donors that already have the /fix command because using /fix all the time gets annoying and having to keep track of the items health my two ideas for this are 1. Make an unbreakable enchant than donors can put on tools with /enchant but these items should never be traded to those without /fix or 2. Make donors not use the health of an item as they use it so tools would never break for donors but the same tool would break for non-donors(for this idea Mabey make a way to toggle it on/off so donors can get some of the achievements)
Personally I think it would be entirely redundant, as donors can use /fix, or for a single point in the point shop you can repair everything in your inventory.
I guess it would be kinda cool, but unbreaking 3 plus /fix means that maybe twice a year I have to type a three letter command in, so I'm not sure an unbreakable item would really be much use.
We will not be making unbreakable items. However doing /fix is tedious, I feel as if unbreakable items would be too OP.
