So will the rarities be tied to the market prices only? It doesn't seem really truthful to claim that, for example, Magmas would be rarer than Golds. Of course the categories could be set so that they would both simply end amongst the rarest dragons, but as it was discussed somewhere just a while ago, trios may not be very hard to get in reality so they perhaps shouldn't be considered that rare. I absolutely do understand, though, that following those prices would make it much easier and more systematic to update the rarity information as the market is an official, on-site feature and not something based on users' thoughts. In any case, allowing some fluctuations definitely sounds wise.

I don't know if this will really add anything to the discussion, but I was also wondering if it would be an option to change the name of the first category, the one for the least rare dragons, to Very common. Then the second one could be Common and the new category could get the name Uncommon.
