Are you talking about the first one? Well, I'm certainly not a master; I wasn't even close to being on the same level as the masters, but wouldn't a normal player wait for 10 dragons to appear and not develop their hero at all? That's just stupid!
Well, you can do that just to test it, but I think a normal player would develop along with the growth of their troops...
I tried it when I was level 20 and my opponent was level 20, and Emerald Archangels just wiped them out.
I haven't tried it on the first one, so I can't say anything about it. How is it and what's it like there.
