That's an interesting perspective. I'm not quite so cleaved to traditional lore myself, and winged demon-drow on dinosaurs sounds awesome to me.

But I think a modular format captures the best of both worlds: THESE medusa can be one thing, THOSE medusa can be another, and YOUR medusa might be one of those or something else, but either way there isn't a single medusa that defines what medusae are for the game, and you're making an active choice whenever you use a medusa about what purpose to use that particular medusa moment for.
Sure, but I think the problem is that the designers can put in the book only one version, and that will be the default.
First of all, what is cool for someone is uncool for others. If they change a creature significantly, there is probably roughly as many people switching from dislike to like as there are switching from like to dislike. At least, if they don't
change what already is, there is a general benefit of continuity between old and new campaign settings and adventures.
That said, if they think that a new concept like "results of trading off 10 years of beauty for ugliness afterward" is cool and worth putting in the book, why applying it to a monster that already has a different characterization? Why not increasing the ties of the Medusa with the
real-world mythology or folklore instead, and leave the new cool idea for another creature (doesn't have to be an entirely new creature, could be an underdeveloped D&D creature without already a real-world myth)?
This is the problem I have... if I think of that trade-off concept by itself, I say why not, a creature like that in a fantasy world has a cool story. But then what the hell it's not the traditional story of a gorgon/medusa anymore! How would you feel if the designers decided that from now on the
Drow are demon-blooded planehopper rogues and the
Tiefling are now spiders-lovers living in the underdark and led by female priestesses? Aren't these two cool concepts for evil humanoid races after all?
