Advertising - Reaching Target Audience

I thought of a way to make advertising on the Ranked players walls more efficient. I'm sure it's been brought up before, though.

What if each of the 3 players walls were dedicated to a certain type of advertising?

Say:
Rank 1 players wall - Advertising for buying and selling of monsters
Rank 2 players wall - Advertising for buying and selling of items (resets, crystals, etc...)
Rank 3 players wall - Advertising for the needing of allies

I feel like this would be a much better stream-lined way of hitting your target demographic, and would help people, at least compared to the Cluster F that it is now. I can't count how many times I've tried to keep re-loading the 1st ranked players wall waiting to see an ad for a player in need of allies, or a players buying crystals.

However, I do understand that it would be impossible to implement such a thing, but one could dream, right?
Just a thought

... or maybe ATeam could implement an actual marketplace, as long as we're dreaming...

can anyone share key time which the time they easily sell their stuff ? lol
for me it's around 12am

"easily"?? For me, it's 13 o'clock on the 12th of never...

lol like anyone would actually follow any rules
