Tirsla,
A question, are you also gathering your own resources as you go up in your crafting levels? Here's why I ask. Crafting and Gathering combined effect the Expert and Master levels of advancement. Here's what I mean:
Expert = can bring up 3 different crafts and/or gathering types (i.e., herb, mining, woodcrafting) to this level - for example, alchemy, herb and mining gathering
Master = can bring up
only 1 choice of crafting or gathering to maximum level
Here's the catch. When you move 1 craft or gathering to Master level, it does
NOT open up a new 3rd Expert slot to move something else into.
Only Planting is independent of the above Expert and Master leveling and I would encourage you to take on planting, too, because as you progress, it will allow you to augment your materials needs for your crafting. You may plant 10 pots at one time as you get to the higher levels. Another thing that many players do is use an alt for their crafting since your class level never comes to bear on the crafting and use their main leveling class to gather mats. I'm one of those, my primary is max capped on all gathering skills and I do alchemy and cooking on two different alts.
Have fun!
