Conversely, since //distr and /lb me are basically the same command, except //distr is more useful because it doesn't require UUI support, and can be set to a specific location instead of the entire world. So if there is no point in //distr why do all players have access to /lb me?
Additionally, I don't see how either command could harm server performance. Even if there was a way to misuse the command, I'm asking for it to be a Builder+ privilege, so there wouldn't be anybody to misuse it, since there are only a few members of the rank, and they all can be trusted to use simple commands like these properly and not abusively.
//distr would be useful because not only does it display the amount of blocks, but it also displays the percentages. This is extremely convenient in the sense that, for example: If I were to make a mountain, and wanted to variate lets say, some Polished and Regular Andesite, as well as some gravel, I wold be able to check the percentage breakdown of each block, and if there is too much of one block (in realistic and aesthetic terms), I would be able to recognize this.
If you still disagree with the usefulness of //distr, I would be willing to compromise and just ask for //count, though I still believe that both of them would be very useful.
