Azure, rusty, and other super dragons: do they live up to the hype?

I'd like to add one observation: It's very easy and without significant losses for 150 Minotaurs to defeat 10 Azure Dragons. Considering that 150 Minotaurs will cost us 90,000 gold, while 10 Azure Dragons cost 300,000 gold plus 200 Mercury, I haven't tested it, but I suspect that Minotaurs could defeat twenty or thirty dragons with the same ease. Given that on most classic maps, it's not that difficult to get 150 Minotaurs, while accumulating Azure Dragons is rarely necessary, and if it is, it's usually tedious, long, and inconvenient... so, perhaps it's better not to think about dragons at all).
