We need an AH

[Cairdeas]

^^ not quite, due to how an auction list works, if you're looking for something specific, you'll ignore the rest, and maybe only notice something on the same page as what you were after in the first place.

However, with the retainer system, something that may not alphabetically lay with another item in an auction list can be discovered accidently on the retainer when you get to them.

It makes crafting all items more rewarding than just the flavour of the month equipment.

Or selling stuff in Sets.

I've done it more then once where I found a retainer selling the body armor I wanted and bought the boots, and gloves to match as well from them without ever returning to the search.
