Apart from my personal opinion, what does a server whipe bring good if the reason why it is considered still isn't solved?
Idk if there are ppl with an upgrade hack, but the biggest problem is the amount of stones and therefore their worth. Bots, the droprate and maybe the takeout of paypal all leads to the point where I could buy 2 purple/greens and 2 white stones with 1 box sold.
Maybe I am unlucky because I needed about +2kkk in overall for my 2 +15s but as someone who cashed in pre open beta and did about 20h of farming it never had been easier. You just buy stones and the supply making the price isn't decreasing.
