Concept - Creating organic/authentic player interactions: Multi-markets

I think this post might here a bit too early.
HWS has something called Commodity Trading which allows high profit gains by the player buying at point A, and then selling at point B. Selling in PvP means often more profit.
It’s sadly disabled this season as there hasn’t been time to set it up, but you should try reading here:

I believe commodity trading will get a rework for next season if I understood it correctly.

Edit:
Also the HWS Marketplace is already quite dynamic regarding Supply and Demand.
I’ve seen gold down at 260-270 some seasons, and up to 500 and above other seasons. Same with many resources, and items. Every season is different.
