That's about the size of it. If you are an end-game player, or even a completionist needing to get every purple recipe, crafting professions, except BioChem offer little. For the mid-game and gearing alts, crafting is okay. For making money, there are opportunities created by the game, and you can take advantage of them. However, pure gathering will always be more profitable than crafting, as it is impossible to dominate the market for any crafted item at the moment. If you make too big a profit on an item, another dozen crafters with banks full of idle materials will come along and undercut you.
