I can see making these available only to convention attendees early on, but I don't think these should be limited to them forever. Not everyone's work schedule allows them to attend Gen Con or DDXP. Is there any chance that these will be made more freely available in the future? Say a year or two after the convention at which they were released? That way, the people who attended the conventions still enjoy the benefit of having been able to benefit from these convention special cards and level up their characters appropriately for a year or two. Considering what's available now, I doubt that everyone will start playing Orcs just because they become available with Goliaths, Warforged, and Minotaurs as generally-available options. And even with two more types of spellscars to choose from, I doubt we'll be seeing too many people sacrificing a feat for them except for RP-driven purposes. Thoughts?
