I swear I posted here before... I looked through the thread however and didn't find any post by Dr. Cox so I think I'll just post again.
I love mining the way it is. I don't mind having to powermine for levels. I just pop in my earphones, turn on the cricket and I mine away. So far I'm having a heap of fun.
I don't think that mining should be changed as a skill. It is meant to be hard to level without focus and it accomplishes that. Not every skill should be another Woocutting or Fishing if you gather things
I do agree that addy/mith rocks are extremely downplayed though. Put them in better areas where banking is a bit easier (mith is located in the guild, but personally it could be better/ore places to mine/bank). And don't get me started on addy... that, at the moment, is definitely not worth mining. Most people (including myself) skip/are going to skip addy/mith for cash and head straight to runs, which is very sad imo. But there is no incentive or reason to actually go out there for an hour and mine these ores, unless you need some cash desperately or you are superheating.
