Stabilizer prices have skyrocketed after 1.5 stocks ran out. That's a ton of crafting materials we're not getting now--one per raid member on HM. Just another incentive to do an ops gone... Thanks.
On the other hand 1.6 introduced a new - cheap - way to get Grade 8 materials, as the now readily available war hero pieces can be reverse engineered to obtain them. Prices may in fact go down in the long run.
