Yup, the conversion is going to be into 3 star colorless evo runes I HOPE! Durandal states "convert" not "sell" so this indicates to me changing the 4 and 5 star into 3 stat. Just sent in my support email and will let you know, if they "convert" into something else I will post here the result. Maybe a few LoL Awakening shards as a good natured gesture perhaps? Now THAT IS LoL.
