The problem with doing mining and herbalism is that you can only track on of those at a time so you end up missing a lot of stuff. You can get around that though by using a resource map add on that every time you gather something it marks the location on the map so you can just keep in that area.

I've got my mage up to 74 now, I'll probably play a different toon tonight just so I can keep him in rested status. Personally I love the mage class. Massive DPS, and great utility. My biggest problem with other classes is travel. It's so nice to just port where ever I want to go.
