Supper effective against ice because it dries it out.
Water is a better conductor of heat than air. An ice cube will melt faster in room temperature water than room temperature air, because the water particles are more dense than the air particles. If anything an air type should be particularly effective against water (evaporates), and only moderately effective against ice and rock.
I think we could add Air, its clearly the type that is missing.
Rather then flying have them use wind based moves.
Not very effective against fire, because it would help boost it.

Thats fair, i thought about evaporation. It also goes well being weak to fire and strong on water.
