I am currently at level 12 with my caster build (a build which I couldn't be happier about, it's _great_ and I am having a blast). So I am just a step away from chosing between water or fire elemental form. Which one makes more sense when you're levelling? Usually fire resistance and fire damage is the natural way to go, but with creeping cold + freezy spray I am actually more inclined to take water elemental form first (even though fire damage is tossed out on a regular basis in most quests).
Any thoughts or advice?
