I suspect it is the miniature
This might rub non-mini-centric DMs and players the wrong way, but many of us who inve heavily in DDM are beyond pleased by the legacy functions of our minis. There would be even more outcry of "they're milking us for cash" if Tiamat suddenly became Gargantuan and everyone needed to go out and buy her Gargantuan collectible mini in order to be "official."
