Availability of HMPs, Riftcinders, Riftdross

[Ladynamine]

I don't understand why they just don't add heavy metal plates, riftdross, and riftcinders to high-tier fights or bcnm's. It would seem to me that would be a lot easier to add to these fights. Plus it adds more variety to what you can kill to get them. You can put the singles Heavy Metal Plates in HKCNM's (at a lower drop rate) and SKCNM's based on difficulty, and put Heavy Metal Pouches on top of singles, Riftdross, and Riftcinders in the High-tier Mission Battlefield fights also based on difficulty of the fight. All of them can be exclusive to be lottery pooled at a low % rate with the droprate to increase on higher difficulties and only 1 type can drop (either a Heavy Metal Plate/pouch, riftdross, or riftcinder will only drop).
