Maybe the developers already have this idea in the works. But just in case, here’s what I have in mind to make this game economy more viable. At some point, players will end up with a surplus of Traitstones that they have no need for. And, if they have a deficit of Traitstones, then they must farm for more which will naturally take some time, or they just might consider buying one of those Traitstone packs at the Shop to save themselves time. Either way, they will continue to receive more surplus stones which in the long run will dissuade players from buying any or continuing to pay for more. Those packs, as we all know, are not cheap. Neither are the costs to operate this game for its growing fan base.
This is where trading comes in. Players have requested it all over this forum. There are some pros and cons with each of them, of course. And I welcome them all to chime in anyway with those ideas so the devs can have a thread devoted to Trade.
For me though, I personally think that this idea is best suited at the Shop. Currently, we can use gems to buy armor, souls, and gold. Glory can buy one of four items in the Rewards tab. Everything else is sold at a price. Now imagine a new tab called Trades. When it opens, you see four panels (i.e., Minor; Major; Runic; Arcane). At the top right corner of the screen is a new currency: Celestial. The amount of Celestial stones you currently possess will be displayed there in that box.
When clicking any one of the four panels below, you will see two buttons in it: Buy and Sell. One Celestial stone can buy you 625 minors, 125 majors, 25 runics, or 5 arcanes of your choice. Just select which panel to buy those stones from. Selling works differently. You basically trade 5 lesser stones for the next higher stone of your choice (e.g., in the Minor panel, 5 minor reds for 1 major brown; In the Major panel, 5 major greens for 1 runic purple; In the Runic panel, 5 runic yellows for 1 arcane; And in the Arcane panel, 5 arcanes for 1 Celestial.). Each time you preform this trade, a window will naturally pop up to confirm the trade. Just click confirm and then simply repeat the process to get whatever you want/ need most from one of those four trait panels.
This form of trading is strictly for those Traitstones.
