When the Way of the Four Elements learns new Elemental Disciplines at 6/11/17, you're able to replace an elemental discipline you already know with a different one.
Is it possible to retrain the Elemental Attunement discipline that you get as a default discipline, or is it only the ones you choose to learn? Aside from roleplay concerns (which is nice from time to time) it's kind of useless and I'd rather pick up another ability.
