Shaman Weapon Buffs in BC?

You will be able to use weapon buffs for each equipped weapon when dual-wielding. When you first buff a weapon, the effect will apply to the main-hand while the second buff will apply to the off-hand. If you reapply the same weapon buff that's already on two weapons, it will replace the buff with the lowest duration remaining. If you buff two weapons with the same weapon buff ability, such as Windfury and then decide that you'd like to replace one with a Rockbiter effect, you'll have a mouse-over option that will allow you to select which hand you wish to buff.
