Bit harsh.
Not their fault that they have a "pathetic" network. There was a time when Emirates had the pathetic network. Karachi and back if i recall. That was it. Despite their pathetic network, those guys managed to lay the groundwork for the airline that you inherited.
I agree that EK network is quite challenging, but equally I would challenge most EK drivers to deliver the result that the A380 crew did in Singapore.
I don't think too many QF Captains would be found wanting at EK, once they were exposed to the network. QF have a rigorous upgrade course as well you know. And once they got over the culture shock, like most EK pilots, they would be extremely capable crew members.
