Should they make Mining - Logging and Fishing easier and faster to level up?

That's not adding challenge, that's making it tedious. It just needs to be fairly balanced.

Now, people say this, but there really is a middle ground.
I personally believe you should have time to get used to every level. Something to get comfortable with. Get familiar.

Sort of in the same lines of setting up a scene. You have to allow time for everything to sink in so your audience gets into the mood. Go too fast and it becomes an unengaging chore, go too slow and it becomes a tedious chore. The balance is in making it an experience the whole way through.
