I've only mined once, but that one time it only took a few seconds to mine the whole ore deposits, how is that bad?
its bad when you go into a mine and start mining ore nods one after another, and it keeps playing same 10+second animation ... if you only mined once its not a problem .. but if u tried clearing every mine in skyrim as i did it can take its toll on you.. like we said though best thing to do is equip picks and pound on the rock
