Counter-heroes in duel mode (3.1).

What do you think about the Ora-Ravenna matchup? I just encountered it against an Albolabris, and I quickly eliminated his fast units, preserved the golems, and naturally started using Armageddon. He messaged me, saying that if I want to use Armageddon, I should do it from the start, and then he disconnected. It seems like the guy couldn't handle it...
I was so surprised that I forgot to save the replay.
