With current amount of Unknown Meteorite Fragment vs the Stat Meteorite Fragment we getting with party run it'll probably sells for a lot less as time goes and make people more discouraged from running it.
Reducing the amount we get to somewhat match the stat fragment will be unfair for newer players later on
My suggestion is to allow breaking or trading one or some unknown meteorite fragment to random stat meteorite fragment.
Though the suggestion might cause problems with the amount of stat fragment we get if running with full party of 12 unique people / master account since on 25 star its 8 unknown frag at least per person (not sure if there's a variety of the amount).
Its just a thought, any feed back or suggestion from other players would be much appreciated.
