Skill bar
A stance is like a toggle skill, and you have one for each of the four main elements. You also have various kinds of elemental attacks skills. Depending on what elemental stance you're on, your elemental skills will do that kind of damage. No more excessive, repetitive or useless skills clogging up your skill book and skill bar. Now you will be flexible and efficient in any zone and raid. Just switch stances and nuke onward!
