They obviously both had a ton of cash sitting around and would rather just send a quick dragon to get a bounce/help on hostile wave since the cash would get FGed instantly anyways. Both served a purpose: the Emerald by BIO + PF +BG and Rage all elites home must have killed a ****load of elites and the Ruby by Rage caused a bounce. Advantage BIO there. Choosing an emerald on the opening wave was pretty smart. I think that was a very strong opening wave by BIO and coupled with the fact that Orcs are garbage this round I'll give the advantage to BIO here in a mintime war.
