I don't agree with the fact that the buffs aren't eligible for dust refunds. The text under the flavor text of a recently nerfed card always was "This card was recently modified, so its Disenchant value has been adjusted.".
Modify means that something is changed in any way. It doesn't matter if the product becomes worse or better. It still is modified.
So either Blizzard changes the text for more accuracy (for example, "weakened" instead of "modified") to show that only these kind of nerfs will be dust refunded or makes buffs eligible for dust refunds like they "promise" according to their sentence under the flavor text.
So, what do you think?
I think it would be nice to get free dust, however I don't think we are owed the dust. Blizzard's flavor text doesn't promise dust refunds for all modified cards; it only explains that a specific card has been selected for full dust refund as a result of a modification to the card. It's up the Blizzard to make a judgment call on what merits a refund. Your example makes a decent case for the buffs triggering a refund. However, when any card is buffed, nerfed, or moved to the hall of fame it affects the utility of many other cards. Nerfing Raiding Party and Preparation lowered the utility of cards like Waggle Pick and Dread Corsair. Should we get dust refunds for cards affected by nerfs that aren't nerfed? Buffs add value to cards, nerfs take away value. That's why they refund dust with nerfs, but don't with buffs. It stinks for players who previously dusted the soon to be buffed cards, but dusting is always a risk. Even seemingly worthless legendary cards like Duskfallen Aviana could suddenly have value when a new set of cards is released.
