Too much dancing

SE really screwed a lot of potential strategies when they made the BLM work the way it does nothing except players have elemental resistances. That was a big screw up on their part.

Elemental resistances are bad design for the players and can be bad for the bosses and encounters. Resistance on the players gates content until an arbitrary resistance minimum is met. For boss encounters I could see this working if handled properly. For example, Ifrit might get increased damage from Ice, normal damage from Lightning and be healed by Fire and so a Black Mage might need to adjust his rotation between encounters. Design like this could give depth to the class, as there would be a huge difference between someone pushing buttons and someone that has taken the time to learn how his skills interact with encounter.

The thing you want to avoid is to just add elemental resistances just for the sake of having an arbitrary number to stack. It's just hard to argue what these stats would really add to the game in terms of depth.
