Leveling crafting whilst leveling DoW/DoM classes

[Wulfyn]

If i recall right, arm and bsm have some of the same recipes, but, doing one in arm isnt going to lvl up your bsm too. Something to consider when it comes to gathering mats for arm, bsm may use some of the same ones. Cross class skills help out, ie: gsm's manipulation, and become important when you want to hq stuff especially at 50+ recipes.
I look at it this way:
If you don't craft or gather, then you can't complain about gear/consumables/items prices.
If you craft and don't gather then you can't complain about mat prices.
If you gather but don't craft, you get the gist

It is nice to be able to make your own stuff cheap to nothing in cost.
