I believe that this is unfair I was buying sunstone in the bazaar and camping the bazaar for sunstone when I saw a level 13 diviner buy sunstone because he said "Oh I just got some sunstone :D" and this isn't fair to us grandmaster crafters who need it this should be made to where only people with the quest for that specific reagent should be able to purchase it. This needs to be addressed with all players.
So basically your mad because someone else got a reagent you wanted. Thats what happens at the bazaar, you often have to be quick otherwise you wont get the reagent. You also have to keep in mind that some players do the crafting quests at low levels, so its possible he needed them for a crafting quest.
