We will be adding some of the more rare stuff to call soon. But as Matt said, it's just 11* and higher now, along with 4 other manual entries. (PGF being one.)
And if I remember right, level 30 resta/support disks are 10 times as likely to drop as any of the other level 30 disks, and drop in a wider range of areas. (each possible level 30 attack tech disk only drops in 1-2 areas)
