Well, today (28/3/19), the Zen Market exchanger is 36 million and raising very fast.
My opinion about that, is that every new incoming module, people become insecure about what to come, what to change, and after that, what to do to keep your toon strong and playable.
So, the best way to prepare yourself for the incoming changes, is to stock as many resources you can (AD, refinement points and Zen). And actually, almost all players think the same thing: Buy Zen with Astral Diamonds. Along these last 2 years, this situation never changed.
A good solution to incentive players to sell more Zen and slowly revert this situation, is to
remove from Zen Store all useful and most used items by the players, and put all of then in Wondrous Bazaar in a new separate tab, (without the VIP 8~12 benefits)
Classic examples (no more or no less Astral Diamonds. It is the true value):
Coalescent Ward = 500k
3x Coalescent Wards pack = 1,35m (suggested new item)
10x Preservation Wards = 50k
90x Preservation Wards = 420k (suggested new item)
Runic Bag = 800k
Companion Upgrade Mini-Pack = 250k (Increase the Tokens to 25, up from 15)
Companion Helper Pack = 700k (Increase the Tokens to 60, up from 45, and change the Bonding Runestone Rank 7 to a Rank 10)
Epic Insignia Pack = 250k
Based on this topic
, create a new box that give you a random transmutable item (armors, cloaks and weapons) called Legacy Treasures Box
= 100k (suggested price)All companions, services, VIP, mounts, packs, enchanted keys, and SH stuff remain in Zen Store normally.
Suggestion about VIP: Add a rank 13 VIP, avaliable only if you brought the 6-months VIP item. Only in the first 2 months after you buy the 6-month VIP, you get one extra enchanted keys per day, and 3 extra Reroll Reward token.
Suggestion about the Auction House: Put again to sell more legendary companions pack like Alphonse Knox, but also add more unique legendary companions with a fixed price (with BoA status, to prevent resseling).
If the idea is to get players to sell more Zen, you will need very strong incentives for it using all the features that the game offers.
That's all. No more ideas ^^ Thank you for reading this.
