This is the GbG store for platinum coins. As you can see the diamonds can be purchased with platinum coins.
Maximum is 1000 diamonds per 70 days? This has to be a mistake as we were told they would refresh more frequently than that.
So let us be very clear. In diamond league you have a 48% chance to win loot after a fight. You have a 1% chance that the loot will be 45 diamonds. So let's make the math simple. If you do 200 fights you can expect to win 45 diamonds on average. If you do 1k fights/day you can expect 225 diamonds. In one season with 10k fights it would be reasonable to expect about 2,225 diamonds.
Now let's assume the image above is not correct and it will refresh every 14 days instead of 70 days. That's still a hard cap of 1000 diamonds or significantly less than half of one GbG season.
So even if they were super generous with platinum coins (yeah right) this can only be seen as a diamond nerf.
This is the death of GbG for diamond cities.
Now you might be thinking that players are going to get so many platinum coins that it will be ok because we can buy lots of diamonds and other stuff. So let's put this in perspective.
It costs 6k platinum coins for 75 fragments of the Somerset Hospital upgrade kit. You need 350 fragments for a complete upgrade.
That means you will need 28k platinum coins for on upgrade kit.
It costs 10k for 100 diamonds. The cost goes up for each purchase so basically it will cost the same number of platinum coins as it does for 200ish diamonds. Do you think they will give enough platinum coins in one GbG season to get the upgrade? No that's ridiculous. So that means the intent right now (I fully expect this to change before live server) is to limit diamonds earned from GbG to less than 200 per season with platinum coins.
We don't know what's in the Gold coin store yet be we do have the silver shop.
Keep in mind the silver will be the most plentiful currency and the shop frequently refreshes so there is probably no need to pay an escalated price for say a tourney ground when you can just wait for the refresh.
This indicates to me that nothing is finalized yet and we're getting a half-baked product.
So we reached out to a contact and asked what the game balance expectations were for highly-active GbG fighters in terms of ability to purchase diamonds with coins earned in one GbG season and the following is the answer.
"While the GbG Trial is a new feature and the balancing is expected to be adjusted over the coming months what should be available in terms of purchase ability is a maximum of 5 silver packs, 3 gold packs and platinum packs. People who cannot fight on high trial levels with high attrition should expect less. We feel the loss of diamonds will be offset by the ability to get the missing fragments of buildings players already have in their inventory."
So by my math that means a very strong GbG player could possibly buy 500+300+200 diamonds or like I said at the top of this post 1k/season or less than half of what we get now.
Edit: We're currently testing this out and the number may have to be revised down to 800 not 1000. We're doing some base tests and will know more in the coming days. July 10, 2025
I hope every player on Beta gets very loud on the forums and discord about this because that's the only way they will change this diamond nerf.
