Should I level DoL classes to 50 before leveling my DoH Classes?

So if you plan on doing some hardcore crafting, gathering won't be used later on. It may be helpful while you're leveling up and it is convenient to have around, but leveling it is a pain

So you're saying it's better to just craft and rely on the fact that the initial investment for the materials (via marketboard) will pale in comparison to the profits made from the items I make. Does this apply to early levels?
