Great Ideas, I don't think burn works well with CNJ/WHM based on the story (CNJ = earth, wind, water), I see where you're going with Elemental Release, I assume using earth/water/fire/wind would give you a buff and that's how it would decide, but then you'd need more elements. As well resistances haven't been very prevalent so far in the game.

I would like to see another water spell, with just the one it feels like an after thought. Either a water bubble that works similar stoneskin but only prevents Magic Damage or maybe a self bubble that's instant cast (so that we can protect ourselves being so enmity intense). Or something a bit like the bubble in brayflox (2nd boss I think) that slows and does damage.
