Casual crafters can still do their crafting slowly without the ring, so should get a battle ring instead. If you are casual about something, say crafting, then you don't need Elite Gear for your crafting - you need casual gear for your crafting. If you want to be an elite crafter, get the elite crafting ring. It makes sense really.
The same applies to other rings. You don't need to be the pinnacle of elite uberness on every job, and even if you were, you wouldn't even need a fancy ring on every job because you're already uber on them. So just pick the ring for the job you consider your most shiny, the ring will give your shiniest job that little extra sparkle. Or if you consider your crafting to be your most precious FFXI activity, you would go with crafting ring.
The old saying "a jack of all trades, a master of none" is true in this case. It is better to excel at one thing, than to try to excel at everything and fail. Sure you can be good at everything, but if you want to be the absolute Top Cat in any field, you have to focus on that one field, and I think the 1/12 choice here reflects that.
