I could see it being exploitive if you could level a skill up to 100 in a few hours, but hitting trees, rocks, or whatever takes a lot of time. You could say parking yourself at a greydwarf spawn point and killing everything that pops up is exploitive too.

That would only prove you a fool. Why punch rocks for hours when you can enjoy the game? Why "park" at a spawn point? I cannot understand for one minute why anybody would work so hard to bypass the planned progression system in a game.
