While I would like more action bars myself, I think that the number of bars required could be reduced if there were some sort of meta-variable on dig bars that would set the terrain and material specializations for all digging actions that have either/both of those stanzas. That would make it easier to get away with using only one bar for digging!

Do not assume that you speak for all just because you are the loudest voice; there are many who disagree that simply have no desire to waste words on you.
