Nib error?

I got blue rex earings 1st PQ then traded them for a 3 att ragged cape.
I thought they dropped heaps, but learnt they do not after 20 more PQ's with 1 saddle drop (Stolen by a DB).
Bad choice or will people farm dis PQ enough that it was a good choice?

They're actually kind-of common, imo. I wouldn't worry too much about it.
