That Shaman Ability I was Talking about

Wowhead Tool tip -
So after i finished the previous post i decided to elaborate a bit on my idea for that shaman melee ability. The idea is that it's a main-hand weapon attack, compliments the off-hand strike of Lava Lash but can benefit all other specs. It will have special effect based on the weapon enchant on it.
Fist/Hammer of the Elements (or some other catchy shaman-y name)
Weapon Attack - Melee - Deals X Damage to main target plus bonus effect based on enchant. Rockbiter - increases damage by and additional y amount. Flametongue - Chance on hit to cause Heat Stroke (or some other fire related name) increases the damage of your next Lava Burst, Lightning Bolt, or Chain Lightning by Z amount. Frost Brand - Chance on hit root target in ice for A seconds. Yes this overlaps with Frozen Power, but this one is more for Elemental PVP, but if Frozen power is moved up, which it should be then Freezes the opponents weapon disarming him for a seconds. Note this is still geared more towards PVP. Windfury - Attack deals nature damage. Increases the damage of next Windfury proc by B amount. Earthliving - Chance on hit heals the enemies target for amount equal to C% of damage dealt. Makes a great self heal, but also could be used to heal tanks, but more suited to a off-heal Shaman in that situation.
The main idea for this is a melee attack that benefits all three specs and doesn't require dual-wielding but adds to the complexity of the shaman rotation. Now shamans are supposed to be simpler than Paladins, but being easier doesn't always make something more fun, there should still be decisions and options to reach the top of the dps charts
