Murky vs Lt Morales
Lt Morales would never lane against Murky or any other hero. If Murky can through the front line to Morales he can do some damage. Against poor teams you can drive Morale off an objective or outright kill her.
One thing to remember is that Fish Tank works against all source of physcial damage. So if you are whaling on Morales you can safely tank Zul'jin going to down on you.
