Just a quick thought. The more exclusive resources such as pearls, embers, and shards. Could you please make it possible to trade these between teammates, even at a loss.
I need Black Pearls and I know most people seem to have plenty. I cannot get them. I have opened so many gold chests, but they are just never there. Perhaps one day I will have extra, when I do I wouldn’t mind sharing them even if I lost a percentage in the exchange.
For example, a new teamamate needs 1,000. If I send him 5,000 and he nets a 1,000 upon receipt that would be fine. Same thing for embers and shards.
