If they had left the BB item drops alone on the NQ/HQ NM's, this would be a non issue--you would have 2 x ~5% chance to get them, one from the KSNM fight(in which you are guaranteed a NQ NM pop item), then one from the NQ NM. Then you would be able to get it from the HQ NM fight IF you get the HQ pop item off the NQ fight.

As they built it now, you can do the KSNM fight, not get a BB item but the pop item, do the NQ NM pop fight, get no BB item AND get NO HQ NM POP--and have to rinse/repeat. If you are unlucky enough to still not get the BB item from the KSNM, you do the NQ and again NOT get the HQ pop item---repeat AGAIN. You finally get to the HQ NM pop because your having crappy luck getting it from the KSNM and CAN'T get it from the NQ NM--and guess what, it's not a 100% drop anymore and you have to do it all AGAIN.

It has the potential to be the same as (or worse) than just spamming the freaking KSNM fights. They should have just left the drop rates alone on the NQ/HQ NM's.
