These two Shaman abilities have the same hotkey icon, it gets sort of confusing. Perhaps change the color of the icon to red or brown for one of them?
In a similar boat is Lightning Breath and Ice Breath a small tweak to the icon would be nice there as well. nothing major, but I just noticed and felt like posting.
Stunner ( Wiz) and Spellbind (Sorc) are yet another example.
