I love the market wards in their current incarnation. I don't see the need to put in a list AH just because a bunch of Verucas are too lazy to spend the extra 30 seconds required to go pick up their item. Honestly, that's all it comes down to.

The only valid concern, to me, is the whole plus item thing. You can't currently tell what is a plus item and what is regular. I'm sure that will be addressed in short order.
