I know it's an old post, but if anyone is still wondering, the reason to set looting rules to common and crafting is to earn the most gold while just grinding levels. You have very limited inventory space, especially in the beginning, and common items stack.

Assuming you just started and don't have any bags yet you have four inventory slots. One will be taken up by whatever crafting material you are looking for. Another may be taken up with food. That leaves you 2-3 open slots. If you aren't babysitting the game, you'll find a few items that probably aren't even the type you need and then your slots are full and you won't find anything else. Those 2-3 items will sell for some silver and you might net a couple gold.

If you only pick up common and crafting items they will just keep stacking. When you come back to the game and sell those big stacks you'll get a lot of gold. Use this gold to buy a weapon, bags, mounts and food. Worry about finding shiny weapons when you're high level.
