Are you living 6-7 years in the past? You'd never go to outdoor area and be alone, always lumped with people from other servers. I can log alts on dead realms and 100% see every mount dropping rare dead due to people from other servers camping them.
Since you're NA you can't really see it, but for EU people feel free to visit Moonglade, Blade's Edge, Khadgar, Saurfang, just few places where I have alts and nothing ever moves on the AH, prices are all over the place, there's no supply and no demand.
I have characters on high pops like Draenor, Silvermoon and Argent Dawn and the difference? Most stuff sells, if it's not some obscure crap. Also if you need to buy something, you can.
For example contracts. On low pops there was often no supplier for the newest 2 contracts until a week later after high pop servers got it, and often they'd be posted for 20x the price than on other servers because if you have monopoly you can price gouge.
