I understand the thematic appeal for having two sets of ingredients one for each raid, but from a practical standpoint I am not a fan. Having these two sets of ingredients, scales and phlogistens, which only drop in one specific raid, fire dragon scales and phlogistens only in the Two Dragon raid and the shadow scale and phlogistens only drop in Temple of Deathwyrm means that only certain characters are run in certain raids. This reduces player choice and options and fun for that matter. Running both raids should be encouraged for all of our characters. Like if I have a light specced healing oriented cleric I would only run the cleric in the fire dragon raid, but never in the shadow raid for example currently. My proposal is to put a merchant in town where we can exchange ingredients on a one to one basis. That would provide an incentive to run both raids on all of our characters. Variety is the spice of life.
