The act of harvesting, mining, logging and..fishing?
I think it should be more than just walking around, finding a spot, and hitting it with a pickaxe or whatever. I loved crafting in XI but hated Helm because it was just down right boring.
The fishing update added some element of a mini game to it but overall it was still boring.
I guess what I'm getting at is, in essence, wanting more out of it.
Why can't it have it's own growth?
Take mining for instance. Along with gaining levels in the art of mining why not have a sort of mini game with it, like controlling the quality of the area so as not to run it dry whilst still trying to gain high quality ores.
Think of it along the lines of "Oh, I want to get the highest grade of that ore but if I put too much focus on getting to it I'll have destroyed the area for awhile, preventing anything from being dug up."
