Grobbulus vs Faerlina for server choice? (H)

Context: Some characters split on realms, I initally transferred my main and some alts to Grob during TBC, but when LK launch hit, I was unable to xfer the rest, as they locked the servers. Thats why they are split now.

• Server pop on Faerlina seems to be larger, so the economy is stronger
• Larger server pop on Faerlina means easier pickup raids, as I have a few alts
• Smaller population on Grob will have an increased demand on trade goods, so they would sell more, if I was primarly sourced stuff myself and sold for profi
• Smaller pop on Grob will mean less competition for gathering
• Smaller pop on Grob means less chances for alt raids, outdoor bosses might be more limited unless they have layers between realms

As someone wholl have pretty much all the professions across my toons, I feel that Grobb would be better as selling goods, but Id be at the mercy of increased demand if I ever needed something from the AH

On the other side, Faerlina would have cheaper prices in the AH, more groups for things, but possible competition for questing during the launch craze/gathering. What would Orc Jesus do?
