There are a ton of comments from people saying they deserve the 2000 dust and they're f2p. The dust is compensation for people who missed out on cards they would have gotten as a result of their pity timer. Meaning they went over some threshold that Blizzard decided would have guaranteed them a valuable card had there not been the bug. If you are f2p and you opened 3 free packs from tavern brawls during the time this took place, you very probably are not owed anything. Unless you were tracking pack openings and know for sure you missed out on your pity legendary, you aren't entitled to anything. Please stop whining.
