That is kind of a confusing response. You're not planning to boost the amount of these things that drop, but you are increasing the opportunities to obtain?

Couple quick ideas:

1) Add these to the list of things you can trade Copper AMAN Vouchers for.
2) Add these to drops from high tier mission battles.
3) Add these as a reward to some Records of Eminence objectives. Could be tricky because if you add to a repeatable objective that could be way too much but if you add to a non-repeatable objective a lot of folks who did these objectives are locked out. Maybe add some Voidwatch related objectives and add them there.
