Anybody had much luck in getting Wind Crystals from Treasure Hunting missions? I have a number of nice purple schematics needing them and in getting Treasure Hunting to 120, using pretty much only Gem hunting missions, I have acquired a grand total of two... Even using Kira Carson, who has a +1 Treasure Hunting crit, hasn't made a huge difference, though she did get the two I acquired. By the time I get more I'll have overlevelled the items I can make. Very frustrating.
