I think the mining guild is fine as it is, and i agree with reversal mining is MUCH more easier now, no colored rocks and having to keep clicking instead of ur player hitting the rock until the ore finally came out, and having only 1 type serves all pickaxe (back then pickaxes didn't have an armor class like bronze, iron, rune etc.) made mining stressing, now you have classed pickaxes and your character mines on 1 click until you get the ore.
