Quote from DeonyiThis is already implemented. Also, please do not post vague suggestions.
I think i explained it pretty well. Each tool will have "stats" of things like mining speed and duribility.
This makes room for possible tiers in the future. For example limestone has mine power (Determines what it can mine.) of 3 and mining speed of 3 and a durriblity of 1. Hopefully i explained something you wern't getting.
