No, stop looking for places to demand dust. This is is incredibly entitled and tedious.
Blizzard has clearly only given out dust for explicit nerfs. Lynessa was a case where the stated intent was different from the actual function, and Blizzard fixed her accordingly which made it a bug fix, not nerf. Tess was explicitly stated to keep casting after death so they fixed (after the erroneous change) her to work they way they said they did. Tag changes and functionality changes (like rule consistency or exploit patching) have never qualified. Why would making cards objectively better count now?
