Some ideas:
* Summon water elemental: ( quite difused, but water elementals rulez) summon 1 water elemental, as the levels increase they gain not only stats, but also som abilities.
* Water spirit form: ( morph) The murloc becomes a water elemental for a certain period of time, still capable of cast it's spells but now he got some bonus health, armor and attack. AND can walk on water
*water fountain: The murloc creates a fissure/geyser like crack on the ground, and water starts to come throught this, all allies that touch the water will gain a moderate health regeneration and a lesser mana regeneration too.
* water ball : (missile) just as a fireball, but it's made of water, and it can both stun the target and knockback him for a while.
* Tidal surf : (AoE) the murloc summons a giant water wave and jumps on it's top, and surfs on it. Then you can or made de direction fix, but a damn powerfull wave, or a weaker, but more long lasting and guideable wave. This second option gives the murloc a quite usefull hunt/escape mechanism, and also it's quite cool a murloc surfing around it's enemies .
