What is the use of having 3 AH's in the game?

Create an alliance toon (DK because of the flight paths), buy what you need from the alliance ah, trade to yourself via the neutral ah, and profit. Problem solved.

A solo player can't buy his own stuff off the AH with an alt. I think that you have missed the part where I described that I do very good business with my lvl 1 toon on the opposite faction, and that thus it's not a problem for me as a boxer.
