Now that I have your attention(kek), I would like to suggest two things:
Renaming Blackrock realm to Warsong, coz simply it's better,when you think about Blackrock, nothing nice comes to your mind,ever since vanilla or even wc3 if you want to go that far,if you know what I mean(Blackrock mountain, warlocks and demon bussines, Blackrock players nowadays....) and Warsong is just a name perfect for a pvp realm. Imho. And cooler.

And another: add option to warmane trade similar like "add to cart" and setting minimum price, which would follow rules already that are now,basically just expanding the existing system.
For example:
person 1 puts his toon on trade with full inventory, all bis gear and w/e, but with extended option of setting the min price he wants for it. Let's say he has a Pala with sm naked on trade which would be 150c,but has included inventory.
And then you Person 2 scout it, choose what would you like to buy more from that inventory, be it trinkets, boots or w/e, thus increasing the price of toon,or you just buy it with sm. Following the rules already implemented regarding price, just giving us the option to buy it for warmane trade set price or you alone increasing it with adding more items.

Second could have been probably explained whole lot easier, but hell..

Sorry for wall of text.
Kind regards, ty for your work :)
