Hi judgement_classicwow, and thanks for the question.As /u/pazorax mentioned earlier, we want there to be some exploration and discovery to this, so I can't dig super deep into exact specifics around when individual quests, items, or rep items will be available. Painting in broad strokes however, Thorium Point and Jintha'alor quests should be available during phase 1. Most quests in Cenarion Hold will be available during phase 5 along with the AQ Gate opening content. The general methodology was to make quests, recipes, items, and the like available when it makes sense to do so and feels relevant to the rest of the available content.
