And if Euron The Sex Machine could get 1,000 pirate ships made presumably in a few months why didn't Qyburn make at least a dozen scorpions?!? Guessing there will be a few more in the next death match.

Frickin' Euron got 1,000 bad ass pirate ships made in what, a couple/few months?!? (Something I don't think you could get done in today's modern age let alone in medieval times). I'd guess some blacksmiths could outfit an army of dragons with armor if the queen demands it.
