I like that idea,
sort of like 'mine until i succeed once' rather than 'mine, then even tho i was unsuccesful, ponder what my next move should/would be'
EDIT: To avoid double-posting i'm making this an edit; guess i wasn't clear, but i didn't mean that you mine forever, or move & continue after succeeding.. just that you stay in place & mine until successful once. (Seems to me for rare ores that's about as fair as the swords with 10 minute repair jobs, and for normal ones it's as fair as the above magic idea--after all, with lower magic skills you fail at spells a LOT, so similar to mining failure.. If it's really a matter of choosing each step after the other, as suggested below, then fights using combat skills should require rapid repeated successive use of attack commands)
But alas i think this topic goes on wishlist.
