This could also open the door to tiered spawns as well---lower tiered ones could drop the items to pop the higher tiered target.
Just as an example, S rank could require a specific drop from an A, or maybe a set from any combination of A, B, and local mobs. Same could be done for A--need to farm drop(s) from B's and/or locals to pop the A's. This way people can farm some items solo and then team up to kill the NM's in a <hopefully> somewhat more organized fashion.
