UPDATE: This appears to be a zoning bug that not everyone has. alot of other ppl are saying their off hand is still broken after re-zoning.
here's a pretty simple exploit i found out by accident on how to dual wield as elemental or resto(i haven't tested it in resto).
1. learn duel spec and make an enhancement spec and elemental spec.
2. switch to your enhance spec and equip both weapons.
3. switch to elemental. as you will see you will have both weapons in their appropriate slots however you have only 1 weapon in your hand and have a broken weapon symbol(see below).
4. teleport to another zone, for example, use your hearth from ironforge to dalaran. you have to switch zones, when i used my hearth while in dalaran it did not work.
5. your broken weapon symbol is gone and you can now benefit from both weapons and weapon enchants, 2 flametongues.
